A shop gave a discount of $3 for every $45 spent. Cindy bought a shirt and paid $180 after the discount.
- What was the price of the shirt before the discount?
- What was the amount that Cindy saved?
(a)
Actual amount paid for every $45 spent
= 45 - 3
= $42
Number of sets of $42 spent
= 180 ÷ 42
= 4 r 12
Price of the shirt before the discount
= 4 x 45 + 12
= 180 + 12
= $192
(b)
Amount that Cindy saved
= 4 x 3
= $12
Answer(s): (a) $192; (b) $12
