A shopping centre gave a discount of $4 for every $15 spent. Cindy bought a vest and paid $140 after the discount.
- What was the price of the vest before the discount?
- What was the amount that Cindy saved?
(a)
Actual amount paid for every $15 spent
= 15 - 4
= $11
Number of sets of $11 spent
= 140 ÷ 11
= 12 r 8
Price of the vest before the discount
= 12 x 15 + 8
= 180 + 8
= $188
(b)
Amount that Cindy saved
= 12 x 4
= $48
Answer(s): (a) $188; (b) $48
