A mall gave a discount of $2 for every $10 spent. Hilda bought a blazer and paid $170 after the discount.
- What was the price of the blazer before the discount?
- What was the amount that Hilda saved?
(a)
Actual amount paid for every $10 spent
= 10 - 2
= $8
Number of sets of $8 spent
= 170 ÷ 8
= 21 r 2
Price of the blazer before the discount
= 21 x 10 + 2
= 210 + 2
= $212
(b)
Amount that Hilda saved
= 21 x 2
= $42
Answer(s): (a) $212; (b) $42
