(a)
Amount to pay at Shop N for every $50 spent
= 50 - 10
= $40
Number of sets of $50 in $410
= 410 ÷ 50
= 8 r 10
Discounted price of the shirt at Shop N
= 8 x 40 + 10
= $330
Discounted price of the shirt at Shop P
= 75% x 410
=
75100 x 410
= $307.50
Amount of savings
= 330 - 307.50
= $22.50
(b)
Number of sets of $40 in $320
= 320 ÷ 40
= 8
Total cost of the vest and the jacket
= 8 x 50
= $400
(c)

Original price of the jacket at Shop P before discount
= 73.50 ÷
75100= $98
If the original price of the jacket at Shop N and Shop P is the same, the original price of the jacket at Shop N is $98.
Number of sets of $50 in $98
= 98 ÷ 50
= 1 r 48
Discounted price of the jacket at Shop N
= 1 x 40 + 48
= $88
Discount given for the jacket at Shop N
= 98 - 88
= $10
Percent discount given to the jacket at Shop N
= 100% x
1098 ≈ 10.2%
Answer(s): (a) $22.50; (b) $400; (c) 10.2%
