Zara wanted to buy a vest. She saw a red vest on sale at 25% discount and a silver vest at 35% discount. Both vests had the same original price before the discounts. To buy the red vest, Zara would need $6.40 more that what she had. So Zara bought the silver vest. After that, she had $19 left.

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

	Red vest	Silver vest
Before	100%	100%
Change	- 25%	- 35%
After	75%	65%

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

Additional amount that Zara needed to pay if she would buy the red vest
= 6.40 + 19
= $25.40

10% →  25.40
100% → ^25.40₁₀ x 100 = 254

Original price of the red vest = $254

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

Price of the silver vest after discount
= ⁶⁵₁₀₀ x 254
= $165.10

Amount that Zara had at first
= 165.10 + 19
= $184.10

Answer(s): (a) $254; (b) $184.10
