Sabrina wanted to buy a jumpsuit. She saw a red jumpsuit on sale at 15% discount and a purple jumpsuit at 30% discount. Both jumpsuits had the same original price before the discounts. To buy the red jumpsuit, Sabrina would need $4.30 more that what she had. So Sabrina bought the purple jumpsuit. After that, she had $20 left.

1. What was the original price of the red jumpsuit?
2. How much money did Sabrina have at first?

	Red jumpsuit	Purple jumpsuit
Before	100%	100%
Change	- 15%	- 30%
After	85%	70%

(a)
Difference in the discount between the red jumpsuit and the purple jumpsuit
= 30% - 15%
= 15%

Additional amount that Sabrina needed to pay if she would buy the red jumpsuit
= 4.30 + 20
= $24.30

15% →  24.30
100% → ^24.30₁₅ x 100 = 162

Original price of the red jumpsuit = $162

(b)
Price of the purple jumpsuit after discount in percentage
= 100% - 30%
= 70%

Price of the purple jumpsuit after discount
= ⁷⁰₁₀₀ x 162
= $113.40

Amount that Sabrina had at first
= 113.40 + 20
= $133.40

Answer(s): (a) $162; (b) $133.40
