A boutique gave a discount of $2 for every $10 spent. Emma bought a dress and paid $140 after the discount.
- What was the price of the dress before the discount?
- What was the amount that Emma saved?
(a)
Actual amount paid for every $10 spent
= 10 - 2
= $8
Number of sets of $8 spent
= 140 ÷ 8
= 17 r 4
Price of the dress before the discount
= 17 x 10 + 4
= 170 + 4
= $174
(b)
Amount that Emma saved
= 17 x 2
= $34
Answer(s): (a) $174; (b) $34
