A shopping centre gave a discount of $4 for every $25 spent. Mary bought a coat and paid $270 after the discount.
- What was the price of the coat before the discount?
- What was the amount that Mary saved?
(a)
Actual amount paid for every $25 spent
= 25 - 4
= $21
Number of sets of $21 spent
= 270 ÷ 21
= 12 r 18
Price of the coat before the discount
= 12 x 25 + 18
= 300 + 18
= $318
(b)
Amount that Mary saved
= 12 x 4
= $48
Answer(s): (a) $318; (b) $48
