Mrs Neave bought a blouse and a ring at a discount. She spent a total of $67.50 on these two items. She spent $33.30 more on the ring than on the blouse.

1. How much did she spend on the ring?
2. The total discount given for the two items was $14.50. She was given a 10% discount for the blouse. What was the percentage discount given for the ring?

(a)
Amount spent on the blouse = 1 u
Amount spent on the ring = 1 u + 33.30

Total amount spent on the blouse and the ring
= 1 u + 1 u + 33.30
= 2 u + 33.30

2 u + 33.30 = 67.50
2 u = 67.50 - 33.30
2 u = 34.20

1 u = 34.20 ÷ 2 = 17.10

Amount that Mrs Neave spent on the ring
= 17.10 + 33.30
= $50.40

(b)

	Blouse	Ring	Total
Original price	100%	$63
Discount	10%  $1.90	$12.60	$14.50
Discounted price	90% $17.10	$50.40	$67.50

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

90% of the price of the blouse = 17.10
1% of the price of the blouse = 17.10 ÷ 90
10% of the price of the blouse = 17.10 ÷ 90 x 10 = 1.90

Discount given for the ring
= 14.50 - 1.90
= $12.60

Original price of the ring
= 50.40 + 12.60
= $63

Percentage discount of the ring
= ^12.60₆₃ x 100%
= 20%

Answer(s): (a) $50.40; (b) 20%
