Yoko wanted to buy a blazer. She saw a silver blazer on sale at 15% discount and a red blazer at 35% discount. Both blazers had the same original price before the discounts. To buy the silver blazer, Yoko would need $7.40 more that what she had. So Yoko bought the red blazer. After that, she had $15 left.

1. What was the original price of the silver blazer?
2. How much money did Yoko have at first?

	Silver blazer	Red blazer
Before	100%	100%
Change	- 15%	- 35%
After	85%	65%

(a)
Difference in the discount between the silver blazer and the red blazer
= 35% - 15%
= 20%

Additional amount that Yoko needed to pay if she would buy the silver blazer
= 7.40 + 15
= $22.40

20% →  22.40
100% → ^22.40₂₀ x 100 = 112

Original price of the silver blazer = $112

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

Price of the red blazer after discount
= ⁶⁵₁₀₀ x 112
= $72.80

Amount that Yoko had at first
= 72.80 + 15
= $87.80

Answer(s): (a) $112; (b) $87.80
