Mrs Oliver bought a jacket and a ring at a discount. She spent a total of $95.40 on these two items. She spent $37.80 more on the ring than on the jacket.

1. How much did she spend on the ring?
2. The total discount given for the two items was $10.60. She was given a 10% discount for the jacket. What was the percentage discount given for the ring?

(a)
Amount spent on the jacket = 1 u
Amount spent on the ring = 1 u + 37.80

Total amount spent on the jacket and the ring
= 1 u + 1 u + 37.80
= 2 u + 37.80

2 u + 37.80 = 95.40
2 u = 95.40 - 37.80
2 u = 57.60

1 u = 57.60 ÷ 2 = 28.80

Amount that Mrs Oliver spent on the ring
= 28.80 + 37.80
= $66.60

(b)

	Jacket	Ring	Total
Original price	100%	$74
Discount	10%  $3.20	$7.40	$10.60
Discounted price	90% $28.80	$66.60	$95.40

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

90% of the price of the jacket = 28.80
1% of the price of the jacket = 28.80 ÷ 90
10% of the price of the jacket = 28.80 ÷ 90 x 10 = 3.20

Discount given for the ring
= 10.60 - 3.20
= $7.40

Original price of the ring
= 66.60 + 7.40
= $74

Percentage discount of the ring
= ^7.40₇₄ x 100%
= 10%

Answer(s): (a) $66.60; (b) 10%
