Zara wanted to buy a jacket. She saw a brown jacket on sale at 25% discount and a black jacket at 35% discount. Both jackets had the same original price before the discounts. To buy the brown jacket, Zara would need $7.40 more that what she had. So Zara bought the black jacket. After that, she had $18 left.

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

	Brown jacket	Black jacket
Before	100%	100%
Change	- 25%	- 35%
After	75%	65%

(a)
Difference in the discount between the brown jacket and the black jacket
= 35% - 25%
= 10%

Additional amount that Zara needed to pay if she would buy the brown jacket
= 7.40 + 18
= $25.40

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

Original price of the brown jacket = $254

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

Price of the black jacket after discount
= ⁶⁵₁₀₀ x 254
= $165.10

Amount that Zara had at first
= 165.10 + 18
= $183.10

Answer(s): (a) $254; (b) $183.10
