Fiona wanted to buy a windbreaker. She saw a brown windbreaker on sale at 15% discount and a silver windbreaker at 35% discount. Both windbreakers had the same original price before the discounts. To buy the brown windbreaker, Fiona would need $8.20 more that what she had. So Fiona bought the silver windbreaker. After that, she had $7 left.

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

	Brown windbreaker	Silver windbreaker
Before	100%	100%
Change	- 15%	- 35%
After	85%	65%

(a)
Difference in the discount between the brown windbreaker and the silver windbreaker
= 35% - 15%
= 20%

Additional amount that Fiona needed to pay if she would buy the brown windbreaker
= 8.20 + 7
= $15.20

20% →  15.20
100% → ^15.20₂₀ x 100 = 76

Original price of the brown windbreaker = $76

(b)
Price of the silver windbreaker after discount in percentage
= 100% - 35%
= 65%

Price of the silver windbreaker after discount
= ⁶⁵₁₀₀ x 76
= $49.40

Amount that Fiona had at first
= 49.40 + 7
= $56.40

Answer(s): (a) $76; (b) $56.40
