A shopping centre gave a discount of $2 for every $15 spent. Kylie bought a sweater and paid $140 after the discount.
- What was the price of the sweater before the discount?
- What was the amount that Kylie saved?
(a)
Actual amount paid for every $15 spent
= 15 - 2
= $13
Number of sets of $13 spent
= 140 ÷ 13
= 10 r 10
Price of the sweater before the discount
= 10 x 15 + 10
= 150 + 10
= $160
(b)
Amount that Kylie saved
= 10 x 2
= $20
Answer(s): (a) $160; (b) $20
