A boutique gave a discount of $4 for every $45 spent. Roshel bought a sweater and paid $130 after the discount.
- What was the price of the sweater before the discount?
- What was the amount that Roshel saved?
(a)
Actual amount paid for every $45 spent
= 45 - 4
= $41
Number of sets of $41 spent
= 130 ÷ 41
= 3 r 7
Price of the sweater before the discount
= 3 x 45 + 7
= 135 + 7
= $142
(b)
Amount that Roshel saved
= 3 x 4
= $12
Answer(s): (a) $142; (b) $12
