Mrs Dylan bought a jumpsuit and a ring at a discount. She spent a total of $88.90 on these two items. She spent $29.50 more on the ring than on the jumpsuit.

1. How much did she spend on the ring?
2. The total discount given for the two items was $18.10. She was given a 10% discount for the jumpsuit. What was the percentage discount given for the ring?

(a)
Amount spent on the jumpsuit = 1 u
Amount spent on the ring = 1 u + 29.50

Total amount spent on the jumpsuit and the ring
= 1 u + 1 u + 29.50
= 2 u + 29.50

2 u + 29.50 = 88.90
2 u = 88.90 - 29.50
2 u = 59.40

1 u = 59.40 ÷ 2 = 29.70

Amount that Mrs Dylan spent on the ring
= 29.70 + 29.50
= $59.20

(b)

	Jumpsuit	Ring	Total
Original price	100%	$74
Discount	10%  $3.30	$14.80	$18.10
Discounted price	90% $29.70	$59.20	$88.90

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

90% of the price of the jumpsuit = 29.70
1% of the price of the jumpsuit = 29.70 ÷ 90
10% of the price of the jumpsuit = 29.70 ÷ 90 x 10 = 3.30

Discount given for the ring
= 18.10 - 3.30
= $14.80

Original price of the ring
= 59.20 + 14.80
= $74

Percentage discount of the ring
= ^14.80₇₄ x 100%
= 20%

Answer(s): (a) $59.20; (b) 20%
