Julie wanted to buy a blazer. She saw a brown blazer on sale at 20% discount and a pink blazer at 30% discount. Both blazers had the same original price before the discounts. To buy the brown blazer, Julie would need $9.60 more that what she had. So Julie bought the pink blazer. After that, she had $15 left.

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

	Brown blazer	Pink blazer
Before	100%	100%
Change	- 20%	- 30%
After	80%	70%

(a)
Difference in the discount between the brown blazer and the pink blazer
= 30% - 20%
= 10%

Additional amount that Julie needed to pay if she would buy the brown blazer
= 9.60 + 15
= $24.60

10% →  24.60
100% → ^24.60₁₀ x 100 = 246

Original price of the brown blazer = $246

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

Price of the pink blazer after discount
= ⁷⁰₁₀₀ x 246
= $172.20

Amount that Julie had at first
= 172.20 + 15
= $187.20

Answer(s): (a) $246; (b) $187.20
