Elyse wanted to buy a jumpsuit. She saw a blue jumpsuit on sale at 15% discount and a red jumpsuit at 25% discount. Both jumpsuits had the same original price before the discounts. To buy the blue jumpsuit, Elyse would need $6.40 more that what she had. So Elyse bought the red jumpsuit. After that, she had $11 left.

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

	Blue jumpsuit	Red jumpsuit
Before	100%	100%
Change	- 15%	- 25%
After	85%	75%

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

Additional amount that Elyse needed to pay if she would buy the blue jumpsuit
= 6.40 + 11
= $17.40

10% →  17.40
100% → ^17.40₁₀ x 100 = 174

Original price of the blue jumpsuit = $174

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

Price of the red jumpsuit after discount
= ⁷⁵₁₀₀ x 174
= $130.50

Amount that Elyse had at first
= 130.50 + 11
= $141.50

Answer(s): (a) $174; (b) $141.50
