Shop H - 25% off Storewide

1. Hilda wants to buy a blazer. The price of the blazer before discount in both shops is $210. What is the savings that Hilda makes if she buys at the shop that sells the same blazer cheaper?
2. Cathy bought a jumpsuit and a cardigan from Shop G and paid $96. What was the total cost of the jumpsuit and the cardigan before the discount?
3. The price of the same cardigan after discount at Shop H is $139.50. Given that the price of the cardigan before discount is the same in both shops, what is the percentage discount given to the cardigan at Shop G? Round off the answer to 1 decimal place.

(a)
Amount to pay at Shop G for every $30 spent
= 30 - 6
= $24

Number of sets of $30 in $210
= 210 ÷ 30
= 7 r 0

Discounted price of the blazer at Shop G
= 7 x 24 + 0
= $168

Discounted price of the blazer at Shop H
= 75% x 210 
= ⁷⁵₁₀₀ x 210 
= $157.50

Amount of savings
= 168 - 157.50
= $10.50

(b)
Number of sets of $24 in $96
= 96 ÷ 24
= 4

Total cost of the jumpsuit and the cardigan
= 4 x 30
= $120

(c)

	Shop G	Shop H
Original Price	$186	$186
Discount	- $36	- 25%
Discounted Price	$150	$139.50

Original price of the cardigan at Shop H before discount
= 139.50 ÷ ⁷⁵₁₀₀
= $186

If the original price of the cardigan at Shop G and Shop H is the same, the original price of the cardigan at Shop G is $186.

Number of sets of $30 in $186
= 186 ÷ 30
= 6 r 6

Discounted price of the cardigan at Shop G
= 6 x 24 + 6
= $150

Discount given for the cardigan at Shop G
= 186 - 150
= $36

Percent discount given to the cardigan at Shop G
= 100% x ³⁶₁₈₆ 
≈ 19.4%

Answer(s): (a) $10.50; (b) $120; (c) 19.4%
