Victoria had some money. She spent 20% on a tour and 40% of her remaining money on a sweater. She had $48 left.
- How much did she have at first?
- If the sweater was bought at a 20% discount, what was the original price of the sweater?
(a)
Percent of Victoria's amount left after she spent on a tour
= 100% - 20%
= 80%
Percent of Victoria's remaining amount left after she spent on the sweater
= 100% - 40%
= 60%
Fraction of Victoria's amount left
= 60% x 80%
=
60100 x
80100=
1225Total amount that Victoria had = 25 u
Amount that Victoria had left = 12 u
12 u = 48
1 u = 48 ÷ 12 = 4
Amount that Victoria had at first
= 25 u
= 25 x 4
= $100
(b)
Fraction of Victoria's amount spent on the sweater
= 40% x 80%
=
40100 x
80100 =
825Amount that Victoria spent on the sweater
= 8 u
= 8 x 4
= $32
Discounted price of the sweater in percent
= 100% - 20%
= 80%
80% of the price of the sweater = 32
1% of the price of the sweater = 32 ÷ 80 = 0.4
100% of the price of the sweater = 100 x 0.4 = 40
Original price of the sweater = $40
Answer(s): (a) $100; (b) $40
