A shop gave a discount of $3 for every $25 spent. Gwen bought a skirt and paid $160 after the discount.
- What was the price of the skirt before the discount?
- What was the amount that Gwen saved?
(a)
Actual amount paid for every $25 spent
= 25 - 3
= $22
Number of sets of $22 spent
= 160 ÷ 22
= 7 r 6
Price of the skirt before the discount
= 7 x 25 + 6
= 175 + 6
= $181
(b)
Amount that Gwen saved
= 7 x 3
= $21
Answer(s): (a) $181; (b) $21
