Household Finance & Major Decisions — Chapter review · Government, Civic Participation & Economics, Grade 12
5 focused units, followed by an evidence workshop, chapter review, and chapter quiz.
Review the key ideas
Budgets, Cash Flow, Saving & Financial Resilience
Cash flow concerns timing. A month can show a positive balance while a bill falls due before income arrives. Stocks of available funds, expected receipts, and commitments should be tracked separately. Financial resilience concerns the ability to respond to changes, not proof that everyone can solve a shortage through one budgeting rule.
Credit, Interest, Loan Terms & Borrowing Costs
APR expresses an annualized credit-cost measure under applicable rules; it is not always identical to a quoted interest rate or every possible charge. The timing, term, fees, repayment schedule, and conditions matter. A simplified annual interest calculation should not be presented as a full legal APR computation for a real contract.
Saving, Investing, Compounding & Risk
Return can include income and changes in value, minus relevant costs under a specified calculation. Nominal return differs from inflation-adjusted purchasing power. Compounding can increase a model balance over time, but a constant rate in a worksheet is a hypothetical assumption rather than a forecast.
Taxes, Withholding, Insurance & Risk Sharing
Withholding is a payment toward an obligation through a specified arrangement; it is not automatically the final amount owed. A refund can return excess payment rather than create a bonus unrelated to prior payments. Records and current official instructions matter for a real filing. The course asks students to interpret fictional statements, not submit a return.
Education, Work & Housing: Comparing Feasible Paths
Education net price subtracts grants or scholarships from the defined cost; loans finance an obligation rather than reduce that cost in the same way. Work offers require hours, deductions, commuting, stability, and other conditions. Housing comparisons distinguish deposits, recurring payments, utilities, travel, and contract terms. One headline price does not describe the whole commitment.
Problem 1
Answer and explanation
The monthly unallocated margin is $200. At the early date, the $80 bill exceeds $50 available cash by $30. These are different measures: the period’s planned balance and a date-specific cash constraint. The packet does not supply a free borrowing option or every actual payment, so a feasible revision needs further timing and resource information.
Subtract the two stated allocations from income.
Compare available cash with the early obligation.
Keep the measures separate.
Response criteria
- Explain the relevant institution or economic concept accurately; show correct calculations where needed.
- Connect supplied evidence and stated assumptions to an explained conclusion.
- Compare feasible options and their effects on different people without stereotypes.
- Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.
Problem 2
Answer and explanation
Income and commitments can use different timing and definitions. A consistent period prevents misleading subtraction, while categories reveal whether saving, spending, and payments are included once. Planned amounts also need comparison with actual receipts and obligations.
Problem 3
Answer and explanation
A repays $1,080 with an $80 simplified charge; B repays $1,200 with a $200 charge. B’s smaller installment does not make it cheaper overall. Payment timing, affordability, and conditions matter, and these totals alone are not formal APR calculations. The packet supports a defined cost comparison rather than a recommendation for a real borrower.
Multiply installment by count.
Subtract $1,000 principal.
Separate total cost from affordability and formal APR.
Response criteria
- Explain the relevant institution or economic concept accurately; show correct calculations where needed.
- Connect supplied evidence and stated assumptions to an explained conclusion.
- Compare feasible options and their effects on different people without stereotypes.
- Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.
Problem 4
Answer and explanation
Fees, timing, term, principal changes, compounding, and other conditions can differ. Compare the complete schedule and amount received, using the applicable disclosure definitions. A single rate does not establish the entire cost or feasibility.
Problem 5
Answer and explanation
The balance is $1,102.50, including $102.50 modeled growth. Simple interest under the comparison gives $1,100. The $2.50 difference comes from growth on prior growth. The model assumes a constant positive rate and excludes actual risk, costs, tax, and inflation; it is not a promised return or an instruction to choose an investment.
Apply 1.05 twice.
Compare with $1,100 simple-interest total.
State excluded risks and costs.
Response criteria
- Explain the relevant institution or economic concept accurately; show correct calculations where needed.
- Connect supplied evidence and stated assumptions to an explained conclusion.
- Compare feasible options and their effects on different people without stereotypes.
- Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.
Problem 6
Answer and explanation
They determine rights, access, and relevant risks. Ownership, debt, and deposits differ, and a resource may lose value or be unavailable when needed. A higher advertised return does not resolve those conditions.
Problem 7
Answer and explanation
Tax is $2,000. The average rate is about 13.33 percent, and the marginal rate within the supplied second range is twenty percent. Applying twenty percent to all income would incorrectly give $3,000. These are invented teaching brackets, not current tax rates or a filing calculation.
Tax each portion separately.
Divide total by taxable income.
Identify the next increment’s bracket.
Response criteria
- Explain the relevant institution or economic concept accurately; show correct calculations where needed.
- Connect supplied evidence and stated assumptions to an explained conclusion.
- Compare feasible options and their effects on different people without stereotypes.
- Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.
Problem 8
Answer and explanation
Only the income above $10,000 in the supplied range faces twenty percent, while the first portion faces ten percent. Total tax is $2,000, giving a 13.33 percent average. The next increment’s rate is twenty percent under this invented schedule.
Problem 9
Answer and explanation
Net price is $4,000. The $3,000 loan finances part of it, leaving $1,000 uncovered under the supplied resources, while creating a $3,000 principal obligation plus any terms not supplied. It does not reduce net price to $1,000. Timing, loan cost, grant conditions, and other expenses remain necessary for a fuller feasibility comparison.
Subtract the grant from cost.
Compare available financing with net price.
Keep borrowed funds separate from price reduction.
Response criteria
- Explain the relevant institution or economic concept accurately; show correct calculations where needed.
- Connect supplied evidence and stated assumptions to an explained conclusion.
- Compare feasible options and their effects on different people without stereotypes.
- Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.
Problem 10
Answer and explanation
A grant can reduce the amount the student must finance under its conditions, while a loan creates a repayment obligation. Financing $3,000 of a $4,000 net price does not make the education cost $1,000. Distinguish cost from current funding.
