Vanessa wanted to buy a skirt. She saw a yellow skirt on sale at 25% discount and a silver skirt at 35% discount. Both skirts had the same original price before the discounts. To buy the yellow skirt, Vanessa would need $8.60 more that what she had. So Vanessa bought the silver skirt. After that, she had $3 left.

1. What was the original price of the yellow skirt?
2. How much money did Vanessa have at first?

	Yellow skirt	Silver skirt
Before	100%	100%
Change	- 25%	- 35%
After	75%	65%

(a)
Difference in the discount between the yellow skirt and the silver skirt
= 35% - 25%
= 10%

Additional amount that Vanessa needed to pay if she would buy the yellow skirt
= 8.60 + 3
= $11.60

10% →  11.60
100% → ^11.60₁₀ x 100 = 116

Original price of the yellow skirt = $116

(b)
Price of the silver skirt after discount in percentage
= 100% - 35%
= 65%

Price of the silver skirt after discount
= ⁶⁵₁₀₀ x 116
= $75.40

Amount that Vanessa had at first
= 75.40 + 3
= $78.40

Answer(s): (a) $116; (b) $78.40
