Ivory wanted to buy a blouse. She saw a green blouse on sale at 25% discount and a grey blouse at 45% discount. Both blouses had the same original price before the discounts. To buy the green blouse, Ivory would need $8.80 more that what she had. So Ivory bought the grey blouse. After that, she had $18 left.

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

	Green blouse	Grey blouse
Before	100%	100%
Change	- 25%	- 45%
After	75%	55%

(a)
Difference in the discount between the green blouse and the grey blouse
= 45% - 25%
= 20%

Additional amount that Ivory needed to pay if she would buy the green blouse
= 8.80 + 18
= $26.80

20% →  26.80
100% → ^26.80₂₀ x 100 = 134

Original price of the green blouse = $134

(b)
Price of the grey blouse after discount in percentage
= 100% - 45%
= 55%

Price of the grey blouse after discount
= ⁵⁵₁₀₀ x 134
= $73.70

Amount that Ivory had at first
= 73.70 + 18
= $91.70

Answer(s): (a) $134; (b) $91.70
