Lucy wanted to buy a dress. She saw a gold dress on sale at 25% discount and a white dress at 40% discount. Both dresses had the same original price before the discounts. To buy the gold dress, Lucy would need $5.80 more that what she had. So Lucy bought the white dress. After that, she had $14 left.

1. What was the original price of the gold dress?
2. How much money did Lucy have at first?

	Gold dress	White dress
Before	100%	100%
Change	- 25%	- 40%
After	75%	60%

(a)
Difference in the discount between the gold dress and the white dress
= 40% - 25%
= 15%

Additional amount that Lucy needed to pay if she would buy the gold dress
= 5.80 + 14
= $19.80

15% →  19.80
100% → ^19.80₁₅ x 100 = 132

Original price of the gold dress = $132

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

Price of the white dress after discount
= ⁶⁰₁₀₀ x 132
= $79.20

Amount that Lucy had at first
= 79.20 + 14
= $93.20

Answer(s): (a) $132; (b) $93.20
