Marion wanted to buy a jacket. She saw a gold jacket on sale at 20% discount and a pink jacket at 30% discount. Both jackets had the same original price before the discounts. To buy the gold jacket, Marion would need $5.70 more that what she had. So Marion bought the pink jacket. After that, she had $7 left.

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

	Gold jacket	Pink jacket
Before	100%	100%
Change	- 20%	- 30%
After	80%	70%

(a)
Difference in the discount between the gold jacket and the pink jacket
= 30% - 20%
= 10%

Additional amount that Marion needed to pay if she would buy the gold jacket
= 5.70 + 7
= $12.70

10% →  12.70
100% → ^12.70₁₀ x 100 = 127

Original price of the gold jacket = $127

(b)
Price of the pink jacket after discount in percentage
= 100% - 30%
= 70%

Price of the pink jacket after discount
= ⁷⁰₁₀₀ x 127
= $88.90

Amount that Marion had at first
= 88.90 + 7
= $95.90

Answer(s): (a) $127; (b) $95.90
