Opal wanted to buy a jacket. She saw a gold jacket on sale at 15% discount and a grey jacket at 25% discount. Both jackets had the same original price before the discounts. To buy the gold jacket, Opal would need $5.20 more that what she had. So Opal bought the grey jacket. After that, she had $15 left.

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

	Gold jacket	Grey jacket
Before	100%	100%
Change	- 15%	- 25%
After	85%	75%

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

Additional amount that Opal needed to pay if she would buy the gold jacket
= 5.20 + 15
= $20.20

10% →  20.20
100% → ^20.20₁₀ x 100 = 202

Original price of the gold jacket = $202

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

Price of the grey jacket after discount
= ⁷⁵₁₀₀ x 202
= $151.50

Amount that Opal had at first
= 151.50 + 15
= $166.50

Answer(s): (a) $202; (b) $166.50
