Hazel wanted to buy a vest. She saw a white vest on sale at 10% discount and a green vest at 20% discount. Both vests had the same original price before the discounts. To buy the white vest, Hazel would need $4.40 more that what she had. So Hazel bought the green vest. After that, she had $2 left.

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

	White vest	Green vest
Before	100%	100%
Change	- 10%	- 20%
After	90%	80%

(a)
Difference in the discount between the white vest and the green vest
= 20% - 10%
= 10%

Additional amount that Hazel needed to pay if she would buy the white vest
= 4.40 + 2
= $6.40

10% →  6.40
100% → ^6.40₁₀ x 100 = 64

Original price of the white vest = $64

(b)
Price of the green vest after discount in percentage
= 100% - 20%
= 80%

Price of the green vest after discount
= ⁸⁰₁₀₀ x 64
= $51.20

Amount that Hazel had at first
= 51.20 + 2
= $53.20

Answer(s): (a) $64; (b) $53.20
