A shop gave a discount of $4 for every $25 spent. Eva bought a sweater and paid $160 after the discount.
- What was the price of the sweater before the discount?
- What was the amount that Eva saved?
(a)
Actual amount paid for every $25 spent
= 25 - 4
= $21
Number of sets of $21 spent
= 160 ÷ 21
= 7 r 13
Price of the sweater before the discount
= 7 x 25 + 13
= 175 + 13
= $188
(b)
Amount that Eva saved
= 7 x 4
= $28
Answer(s): (a) $188; (b) $28
