Nora wanted to buy a windbreaker. She saw a silver windbreaker on sale at 10% discount and a gold windbreaker at 25% discount. Both windbreakers had the same original price before the discounts. To buy the silver windbreaker, Nora would need $5.90 more that what she had. So Nora bought the gold windbreaker. After that, she had $4 left.

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

	Silver windbreaker	Gold windbreaker
Before	100%	100%
Change	- 10%	- 25%
After	90%	75%

(a)
Difference in the discount between the silver windbreaker and the gold windbreaker
= 25% - 10%
= 15%

Additional amount that Nora needed to pay if she would buy the silver windbreaker
= 5.90 + 4
= $9.90

15% →  9.90
100% → ^9.90₁₅ x 100 = 66

Original price of the silver windbreaker = $66

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

Price of the gold windbreaker after discount
= ⁷⁵₁₀₀ x 66
= $49.50

Amount that Nora had at first
= 49.50 + 4
= $53.50

Answer(s): (a) $66; (b) $53.50
