Kimberly wanted to buy a blouse. She saw a pink blouse on sale at 20% discount and a blue blouse at 35% discount. Both blouses had the same original price before the discounts. To buy the pink blouse, Kimberly would need $8.40 more that what she had. So Kimberly bought the blue blouse. After that, she had $18 left.

1. What was the original price of the pink blouse?
2. How much money did Kimberly have at first?

	Pink blouse	Blue blouse
Before	100%	100%
Change	- 20%	- 35%
After	80%	65%

(a)
Difference in the discount between the pink blouse and the blue blouse
= 35% - 20%
= 15%

Additional amount that Kimberly needed to pay if she would buy the pink blouse
= 8.40 + 18
= $26.40

15% →  26.40
100% → ^26.40₁₅ x 100 = 176

Original price of the pink blouse = $176

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

Price of the blue blouse after discount
= ⁶⁵₁₀₀ x 176
= $114.40

Amount that Kimberly had at first
= 114.40 + 18
= $132.40

Answer(s): (a) $176; (b) $132.40
