Barbara wanted to buy a skirt. She saw a gold skirt on sale at 25% discount and a white skirt at 35% discount. Both skirts had the same original price before the discounts. To buy the gold skirt, Barbara would need $9.80 more that what she had. So Barbara bought the white skirt. After that, she had $1 left.

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

	Gold skirt	White skirt
Before	100%	100%
Change	- 25%	- 35%
After	75%	65%

(a)
Difference in the discount between the gold skirt and the white skirt
= 35% - 25%
= 10%

Additional amount that Barbara needed to pay if she would buy the gold skirt
= 9.80 + 1
= $10.80

10% →  10.80
100% → ^10.80₁₀ x 100 = 108

Original price of the gold skirt = $108

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

Price of the white skirt after discount
= ⁶⁵₁₀₀ x 108
= $70.20

Amount that Barbara had at first
= 70.20 + 1
= $71.20

Answer(s): (a) $108; (b) $71.20
