Mrs Perry bought a blazer and a ring at a discount. She spent a total of $85.90 on these two items. She spent $24.70 more on the ring than on the blazer.

1. How much did she spend on the ring?
2. The total discount given for the two items was $27.10. She was given a 10% discount for the blazer. What was the percentage discount given for the ring?

(a)
Amount spent on the blazer = 1 u
Amount spent on the ring = 1 u + 24.70

Total amount spent on the blazer and the ring
= 1 u + 1 u + 24.70
= 2 u + 24.70

2 u + 24.70 = 85.90
2 u = 85.90 - 24.70
2 u = 61.20

1 u = 61.20 ÷ 2 = 30.60

Amount that Mrs Perry spent on the ring
= 30.60 + 24.70
= $55.30

(b)

	Blazer	Ring	Total
Original price	100%	$79
Discount	10%  $3.40	$23.70	$27.10
Discounted price	90% $30.60	$55.30	$85.90

Discounted price of the blazer
= 100% - 10%
= 90%

90% of the price of the blazer = 30.60
1% of the price of the blazer = 30.60 ÷ 90
10% of the price of the blazer = 30.60 ÷ 90 x 10 = 3.40

Discount given for the ring
= 27.10 - 3.40
= $23.70

Original price of the ring
= 55.30 + 23.70
= $79

Percentage discount of the ring
= ^23.70₇₉ x 100%
= 30%

Answer(s): (a) $55.30; (b) 30%
