Linda wanted to buy a windbreaker. She saw a pink windbreaker on sale at 25% discount and a yellow windbreaker at 45% discount. Both windbreakers had the same original price before the discounts. To buy the pink windbreaker, Linda would need $8.80 more that what she had. So Linda bought the yellow windbreaker. After that, she had $2 left.

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

	Pink windbreaker	Yellow windbreaker
Before	100%	100%
Change	- 25%	- 45%
After	75%	55%

(a)
Difference in the discount between the pink windbreaker and the yellow windbreaker
= 45% - 25%
= 20%

Additional amount that Linda needed to pay if she would buy the pink windbreaker
= 8.80 + 2
= $10.80

20% →  10.80
100% → ^10.80₂₀ x 100 = 54

Original price of the pink windbreaker = $54

(b)
Price of the yellow windbreaker after discount in percentage
= 100% - 45%
= 55%

Price of the yellow windbreaker after discount
= ⁵⁵₁₀₀ x 54
= $29.70

Amount that Linda had at first
= 29.70 + 2
= $31.70

Answer(s): (a) $54; (b) $31.70
