A mall gave a discount of $3 for every $20 spent. Mary bought a shirt and paid $140 after the discount.
- What was the price of the shirt before the discount?
- What was the amount that Mary saved?
(a)
Actual amount paid for every $20 spent
= 20 - 3
= $17
Number of sets of $17 spent
= 140 ÷ 17
= 8 r 4
Price of the shirt before the discount
= 8 x 20 + 4
= 160 + 4
= $164
(b)
Amount that Mary saved
= 8 x 3
= $24
Answer(s): (a) $164; (b) $24
