Sarah had some money. She spent 40% on a tour and 25% of her remaining money on a jumpsuit. She had $81 left.
- How much did she have at first?
- If the jumpsuit was bought at a 25% discount, what was the original price of the jumpsuit?
(a)
Percent of Sarah's amount left after she spent on a tour
= 100% - 40%
= 60%
Percent of Sarah's remaining amount left after she spent on the jumpsuit
= 100% - 25%
= 75%
Fraction of Sarah's amount left
= 75% x 60%
=
75100 x
60100=
920Total amount that Sarah had = 20 u
Amount that Sarah had left = 9 u
9 u = 81
1 u = 81 ÷ 9 = 9
Amount that Sarah had at first
= 20 u
= 20 x 9
= $180
(b)
Fraction of Sarah's amount spent on the jumpsuit
= 25% x 60%
=
25100 x
60100 =
320Amount that Sarah spent on the jumpsuit
= 3 u
= 3 x 9
= $27
Discounted price of the jumpsuit in percent
= 100% - 25%
= 75%
75% of the price of the jumpsuit = 27
1% of the price of the jumpsuit = 27 ÷ 75 = 0.36
100% of the price of the jumpsuit = 100 x 0.36 = 36
Original price of the jumpsuit = $36
Answer(s): (a) $180; (b) $36
