Mrs Ben bought a dress and a ring at a discount. She spent a total of $62.50 on these two items. She spent $40.10 more on the ring than on the dress.

1. How much did she spend on the ring?
2. The total discount given for the two items was $8.50. She was given a 20% discount for the dress. What was the percentage discount given for the ring?

(a)
Amount spent on the dress = 1 u
Amount spent on the ring = 1 u + 40.10

Total amount spent on the dress and the ring
= 1 u + 1 u + 40.10
= 2 u + 40.10

2 u + 40.10 = 62.50
2 u = 62.50 - 40.10
2 u = 22.40

1 u = 22.40 ÷ 2 = 11.20

Amount that Mrs Ben spent on the ring
= 11.20 + 40.10
= $51.30

(b)

	Dress	Ring	Total
Original price	100%	$57
Discount	20%  $2.80	$5.70	$8.50
Discounted price	80% $11.20	$51.30	$62.50

Discounted price of the dress
= 100% - 20%
= 80%

80% of the price of the dress = 11.20
1% of the price of the dress = 11.20 ÷ 80
20% of the price of the dress = 11.20 ÷ 80 x 20 = 2.80

Discount given for the ring
= 8.50 - 2.80
= $5.70

Original price of the ring
= 51.30 + 5.70
= $57

Percentage discount of the ring
= ^5.70₅₇ x 100%
= 10%

Answer(s): (a) $51.30; (b) 10%
