A shopping centre gave a discount of $2 for every $30 spent. Kathy bought a sweater and paid $150 after the discount.
- What was the price of the sweater before the discount?
- What was the amount that Kathy saved?
(a)
Actual amount paid for every $30 spent
= 30 - 2
= $28
Number of sets of $28 spent
= 150 ÷ 28
= 5 r 10
Price of the sweater before the discount
= 5 x 30 + 10
= 150 + 10
= $160
(b)
Amount that Kathy saved
= 5 x 2
= $10
Answer(s): (a) $160; (b) $10
