Esther wanted to buy a blazer. She saw a red blazer on sale at 10% discount and a blue blazer at 25% discount. Both blazers had the same original price before the discounts. To buy the red blazer, Esther would need $9.10 more that what she had. So Esther bought the blue blazer. After that, she had $5 left.

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

	Red blazer	Blue blazer
Before	100%	100%
Change	- 10%	- 25%
After	90%	75%

(a)
Difference in the discount between the red blazer and the blue blazer
= 25% - 10%
= 15%

Additional amount that Esther needed to pay if she would buy the red blazer
= 9.10 + 5
= $14.10

15% →  14.10
100% → ^14.10₁₅ x 100 = 94

Original price of the red blazer = $94

(b)
Price of the blue blazer after discount in percentage
= 100% - 25%
= 75%

Price of the blue blazer after discount
= ⁷⁵₁₀₀ x 94
= $70.50

Amount that Esther had at first
= 70.50 + 5
= $75.50

Answer(s): (a) $94; (b) $75.50
