A shopping centre gave a discount of $3 for every $45 spent. Barbara bought a sweater and paid $240 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 $45 spent
= 45 - 3
= $42
Number of sets of $42 spent
= 240 ÷ 42
= 5 r 30
Price of the sweater before the discount
= 5 x 45 + 30
= 225 + 30
= $255
(b)
Amount that Barbara saved
= 5 x 3
= $15
Answer(s): (a) $255; (b) $15
