Mrs Eric bought a dress and a ring at a discount. She spent a total of $64.80 on these two items. She spent $29.60 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 $16.20. 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 + 29.60

Total amount spent on the dress and the ring
= 1 u + 1 u + 29.60
= 2 u + 29.60

2 u + 29.60 = 64.80
2 u = 64.80 - 29.60
2 u = 35.20

1 u = 35.20 ÷ 2 = 17.60

Amount that Mrs Eric spent on the ring
= 17.60 + 29.60
= $47.20

(b)

	Dress	Ring	Total
Original price	100%	$59
Discount	20%  $4.40	$11.80	$16.20
Discounted price	80% $17.60	$47.20	$64.80

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

80% of the price of the dress = 17.60
1% of the price of the dress = 17.60 ÷ 80
20% of the price of the dress = 17.60 ÷ 80 x 20 = 4.40

Discount given for the ring
= 16.20 - 4.40
= $11.80

Original price of the ring
= 47.20 + 11.80
= $59

Percentage discount of the ring
= ^11.80₅₉ x 100%
= 20%

Answer(s): (a) $47.20; (b) 20%
