A shop gave a discount of $2 for every $30 spent. Gwen bought a blouse and paid $130 after the discount.
- What was the price of the blouse before the discount?
- What was the amount that Gwen saved?
(a)
Actual amount paid for every $30 spent
= 30 - 2
= $28
Number of sets of $28 spent
= 130 ÷ 28
= 4 r 18
Price of the blouse before the discount
= 4 x 30 + 18
= 120 + 18
= $138
(b)
Amount that Gwen saved
= 4 x 2
= $8
Answer(s): (a) $138; (b) $8
