A shop gave a discount of $2 for every $30 spent. Barbara bought a sweater and paid $110 after the discount.
- What was the price of the sweater before the discount?
- What was the amount that Barbara saved?
(a)
Actual amount paid for every $30 spent
= 30 - 2
= $28
Number of sets of $28 spent
= 110 ÷ 28
= 3 r 26
Price of the sweater before the discount
= 3 x 30 + 26
= 90 + 26
= $116
(b)
Amount that Barbara saved
= 3 x 2
= $6
Answer(s): (a) $116; (b) $6
