Elyse wanted to buy a blouse. She saw a blue blouse on sale at 20% discount and a green blouse at 30% discount. Both blouses had the same original price before the discounts. To buy the blue blouse, Elyse would need $9.60 more that what she had. So Elyse bought the green blouse. After that, she had $16 left.

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

	Blue blouse	Green blouse
Before	100%	100%
Change	- 20%	- 30%
After	80%	70%

(a)
Difference in the discount between the blue blouse and the green blouse
= 30% - 20%
= 10%

Additional amount that Elyse needed to pay if she would buy the blue blouse
= 9.60 + 16
= $25.60

10% →  25.60
100% → ^25.60₁₀ x 100 = 256

Original price of the blue blouse = $256

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

Price of the green blouse after discount
= ⁷⁰₁₀₀ x 256
= $179.20

Amount that Elyse had at first
= 179.20 + 16
= $195.20

Answer(s): (a) $256; (b) $195.20
