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.
