(a)
Amount to pay at Stall H for every $40 spent
= 40 - 8
= $32
Number of sets of $40 in $150
= 150 ÷ 40
= 3 r 30
Discounted price of the coat at Stall H
= 3 x 32 + 30
= $126
Discounted price of the coat at Stall J
= 75% x 150
=
75100 x 150
= $112.50
Amount of savings
= 126 - 112.50
= $13.50
(b)
Number of sets of $32 in $224
= 224 ÷ 32
= 7
Total cost of the dress and the shirt
= 7 x 40
= $280
(c)

Original price of the shirt at Stall J before discount
= 121.50 ÷
75100= $162
If the original price of the shirt at Stall H and Stall J is the same, the original price of the shirt at Stall H is $162.
Number of sets of $40 in $162

= $130
Discount given for the shirt at Stall H
= 162 - 130
= $32
Percent discount given to the shirt at Stall H
= 100% x
32162 ≈ 19.8%
Answer(s): (a) $13.50; (b) $280; (c) 19.8%
