Dana wanted to buy a jumpsuit. She saw a brown jumpsuit on sale at 15% discount and a grey jumpsuit at 25% discount. Both jumpsuits had the same original price before the discounts. To buy the brown jumpsuit, Dana would need $9.60 more that what she had. So Dana bought the grey jumpsuit. After that, she had $15 left.

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

	Brown jumpsuit	Grey jumpsuit
Before	100%	100%
Change	- 15%	- 25%
After	85%	75%

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

Additional amount that Dana needed to pay if she would buy the brown jumpsuit
= 9.60 + 15
= $24.60

10% →  24.60
100% → ^24.60₁₀ x 100 = 246

Original price of the brown jumpsuit = $246

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

Price of the grey jumpsuit after discount
= ⁷⁵₁₀₀ x 246
= $184.50

Amount that Dana had at first
= 184.50 + 15
= $199.50

Answer(s): (a) $246; (b) $199.50
