A shop gave a discount of $3 for every $25 spent. Erika bought a jacket and paid $100 after the discount.
- What was the price of the jacket before the discount?
- What was the amount that Erika saved?
(a)
Actual amount paid for every $25 spent
= 25 - 3
= $22
Number of sets of $22 spent
= 100 ÷ 22
= 4 r 12
Price of the jacket before the discount
= 4 x 25 + 12
= 100 + 12
= $112
(b)
Amount that Erika saved
= 4 x 3
= $12
Answer(s): (a) $112; (b) $12
