Julie wanted to buy a blouse. She saw a grey blouse on sale at 20% discount and a silver blouse at 30% discount. Both blouses had the same original price before the discounts. To buy the grey blouse, Julie would need $8.40 more that what she had. So Julie bought the silver blouse. After that, she had $14 left.

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

	Grey blouse	Silver blouse
Before	100%	100%
Change	- 20%	- 30%
After	80%	70%

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

Additional amount that Julie needed to pay if she would buy the grey blouse
= 8.40 + 14
= $22.40

10% →  22.40
100% → ^22.40₁₀ x 100 = 224

Original price of the grey blouse = $224

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

Price of the silver blouse after discount
= ⁷⁰₁₀₀ x 224
= $156.80

Amount that Julie had at first
= 156.80 + 14
= $170.80

Answer(s): (a) $224; (b) $170.80
