Diana wanted to buy a blazer. She saw a white blazer on sale at 20% discount and a grey blazer at 40% discount. Both blazers had the same original price before the discounts. To buy the white blazer, Diana would need $6.60 more that what she had. So Diana bought the grey blazer. After that, she had $2 left.

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

	White blazer	Grey blazer
Before	100%	100%
Change	- 20%	- 40%
After	80%	60%

(a)
Difference in the discount between the white blazer and the grey blazer
= 40% - 20%
= 20%

Additional amount that Diana needed to pay if she would buy the white blazer
= 6.60 + 2
= $8.60

20% →  8.60
100% → ^8.60₂₀ x 100 = 43

Original price of the white blazer = $43

(b)
Price of the grey blazer after discount in percentage
= 100% - 40%
= 60%

Price of the grey blazer after discount
= ⁶⁰₁₀₀ x 43
= $25.80

Amount that Diana had at first
= 25.80 + 2
= $27.80

Answer(s): (a) $43; (b) $27.80
