2 questions in the course bank use Discount, in Proportional Reasoning with Percents.
Problem 1
After a 25% discount, a game costs $36. What was the original price?
Worked answer
48
Sale price is 75% of the original
original × 0.75 = 36
36 ÷ 0.75 = 48
Check: 48 × 0.75 = 36 ✓
Problem 2
A coat is marked down 30%, then another 10% off the sale price. What single percent discount is this equal to?
Worked answer
37
0.70 × 0.90 = 0.63
You pay 63%, so the discount is 100% - 63% = 37%
Not 40% — the second cut applies to a smaller amount.
