Raeann wanted to buy a windbreaker. She saw a red windbreaker on sale at 25% discount and a gold windbreaker at 35% discount. Both windbreakers had the same original price before the discounts. To buy the red windbreaker, Raeann would need $4.20 more that what she had. So Raeann bought the gold windbreaker. After that, she had $5 left.

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

	Red windbreaker	Gold windbreaker
Before	100%	100%
Change	- 25%	- 35%
After	75%	65%

(a)
Difference in the discount between the red windbreaker and the gold windbreaker
= 35% - 25%
= 10%

Additional amount that Raeann needed to pay if she would buy the red windbreaker
= 4.20 + 5
= $9.20

10% →  9.20
100% → ^9.20₁₀ x 100 = 92

Original price of the red windbreaker = $92

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

Price of the gold windbreaker after discount
= ⁶⁵₁₀₀ x 92
= $59.80

Amount that Raeann had at first
= 59.80 + 5
= $64.80

Answer(s): (a) $92; (b) $64.80
