Wendy wanted to buy a vest. She saw a black vest on sale at 20% discount and a gold vest at 40% discount. Both vests had the same original price before the discounts. To buy the black vest, Wendy would need $9.60 more that what she had. So Wendy bought the gold vest. After that, she had $14 left.

1. What was the original price of the black vest?
2. How much money did Wendy have at first?

	Black vest	Gold vest
Before	100%	100%
Change	- 20%	- 40%
After	80%	60%

(a)
Difference in the discount between the black vest and the gold vest
= 40% - 20%
= 20%

Additional amount that Wendy needed to pay if she would buy the black vest
= 9.60 + 14
= $23.60

20% →  23.60
100% → ^23.60₂₀ x 100 = 118

Original price of the black vest = $118

(b)
Price of the gold vest after discount in percentage
= 100% - 40%
= 60%

Price of the gold vest after discount
= ⁶⁰₁₀₀ x 118
= $70.80

Amount that Wendy had at first
= 70.80 + 14
= $84.80

Answer(s): (a) $118; (b) $84.80
