Mrs Daniel bought a skirt and a ring at a discount. She spent a total of $84.90 on these two items. She spent $50.10 more on the ring than on the skirt.

1. How much did she spend on the ring?
2. The total discount given for the two items was $19.10. She was given a 40% discount for the skirt. What was the percentage discount given for the ring?

(a)
Amount spent on the skirt = 1 u
Amount spent on the ring = 1 u + 50.10

Total amount spent on the skirt and the ring
= 1 u + 1 u + 50.10
= 2 u + 50.10

2 u + 50.10 = 84.90
2 u = 84.90 - 50.10
2 u = 34.80

1 u = 34.80 ÷ 2 = 17.40

Amount that Mrs Daniel spent on the ring
= 17.40 + 50.10
= $67.50

(b)

	Skirt	Ring	Total
Original price	100%	$75
Discount	40%  $11.60	$7.50	$19.10
Discounted price	60% $17.40	$67.50	$84.90

Discounted price of the skirt
= 100% - 40%
= 60%

60% of the price of the skirt = 17.40
1% of the price of the skirt = 17.40 ÷ 60
40% of the price of the skirt = 17.40 ÷ 60 x 40 = 11.60

Discount given for the ring
= 19.10 - 11.60
= $7.50

Original price of the ring
= 67.50 + 7.50
= $75

Percentage discount of the ring
= ^7.50₇₅ x 100%
= 10%

Answer(s): (a) $67.50; (b) 10%
