Yen wanted to buy a blouse. She saw a yellow blouse on sale at 25% discount and a gold blouse at 40% discount. Both blouses had the same original price before the discounts. To buy the yellow blouse, Yen would need $9.60 more that what she had. So Yen bought the gold blouse. After that, she had $6 left.

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

	Yellow blouse	Gold blouse
Before	100%	100%
Change	- 25%	- 40%
After	75%	60%

(a)
Difference in the discount between the yellow blouse and the gold blouse
= 40% - 25%
= 15%

Additional amount that Yen needed to pay if she would buy the yellow blouse
= 9.60 + 6
= $15.60

15% →  15.60
100% → ^15.60₁₅ x 100 = 104

Original price of the yellow blouse = $104

(b)
Price of the gold blouse after discount in percentage
= 100% - 40%
= 60%

Price of the gold blouse after discount
= ⁶⁰₁₀₀ x 104
= $62.40

Amount that Yen had at first
= 62.40 + 6
= $68.40

Answer(s): (a) $104; (b) $68.40
