Mrs Ivan bought a jumpsuit and a ring at a discount. She spent a total of $84.70 on these two items. She spent $14.50 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 $16.30. 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 + 14.50

Total amount spent on the jumpsuit and the ring
= 1 u + 1 u + 14.50
= 2 u + 14.50

2 u + 14.50 = 84.70
2 u = 84.70 - 14.50
2 u = 70.20

1 u = 70.20 ÷ 2 = 35.10

Amount that Mrs Ivan spent on the ring
= 35.10 + 14.50
= $49.60

(b)

	Jumpsuit	Ring	Total
Original price	100%	$62
Discount	10%  $3.90	$12.40	$16.30
Discounted price	90% $35.10	$49.60	$84.70

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

90% of the price of the jumpsuit = 35.10
1% of the price of the jumpsuit = 35.10 ÷ 90
10% of the price of the jumpsuit = 35.10 ÷ 90 x 10 = 3.90

Discount given for the ring
= 16.30 - 3.90
= $12.40

Original price of the ring
= 49.60 + 12.40
= $62

Percentage discount of the ring
= ^12.40₆₂ x 100%
= 20%

Answer(s): (a) $49.60; (b) 20%
