Esther wanted to buy a windbreaker. She saw a gold windbreaker on sale at 20% discount and a white windbreaker at 30% discount. Both windbreakers had the same original price before the discounts. To buy the gold windbreaker, Esther would need $8.90 more that what she had. So Esther bought the white windbreaker. After that, she had $14 left.

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

	Gold windbreaker	White windbreaker
Before	100%	100%
Change	- 20%	- 30%
After	80%	70%

(a)
Difference in the discount between the gold windbreaker and the white windbreaker
= 30% - 20%
= 10%

Additional amount that Esther needed to pay if she would buy the gold windbreaker
= 8.90 + 14
= $22.90

10% →  22.90
100% → ^22.90₁₀ x 100 = 229

Original price of the gold windbreaker = $229

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

Price of the white windbreaker after discount
= ⁷⁰₁₀₀ x 229
= $160.30

Amount that Esther had at first
= 160.30 + 14
= $174.30

Answer(s): (a) $229; (b) $174.30
