A stall gave a discount of $4 for every $30 spent. Olivia bought a windbreaker and paid $120 after the discount.
- What was the price of the windbreaker before the discount?
- What was the amount that Olivia saved?
(a)
Actual amount paid for every $30 spent
= 30 - 4
= $26
Number of sets of $26 spent
= 120 ÷ 26
= 4 r 16
Price of the windbreaker before the discount
= 4 x 30 + 16
= 120 + 16
= $136
(b)
Amount that Olivia saved
= 4 x 4
= $16
Answer(s): (a) $136; (b) $16
