Jen wanted to buy a blouse. She saw a pink blouse on sale at 10% discount and a purple blouse at 25% discount. Both blouses had the same original price before the discounts. To buy the pink blouse, Jen would need $5.90 more that what she had. So Jen bought the purple blouse. After that, she had $7 left.

1. What was the original price of the pink blouse?
2. How much money did Jen have at first?

	Pink blouse	Purple blouse
Before	100%	100%
Change	- 10%	- 25%
After	90%	75%

(a)
Difference in the discount between the pink blouse and the purple blouse
= 25% - 10%
= 15%

Additional amount that Jen needed to pay if she would buy the pink blouse
= 5.90 + 7
= $12.90

15% →  12.90
100% → ^12.90₁₅ x 100 = 86

Original price of the pink blouse = $86

(b)
Price of the purple blouse after discount in percentage
= 100% - 25%
= 75%

Price of the purple blouse after discount
= ⁷⁵₁₀₀ x 86
= $64.50

Amount that Jen had at first
= 64.50 + 7
= $71.50

Answer(s): (a) $86; (b) $71.50
