Irene wanted to buy a blazer. She saw a pink blazer on sale at 20% discount and a green blazer at 30% discount. Both blazers had the same original price before the discounts. To buy the pink blazer, Irene would need $9.30 more that what she had. So Irene bought the green blazer. After that, she had $19 left.

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

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

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

Additional amount that Irene needed to pay if she would buy the pink blazer
= 9.30 + 19
= $28.30

10% →  28.30
100% → ^28.30₁₀ x 100 = 283

Original price of the pink blazer = $283

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

Price of the green blazer after discount
= ⁷⁰₁₀₀ x 283
= $198.10

Amount that Irene had at first
= 198.10 + 19
= $217.10

Answer(s): (a) $283; (b) $217.10
