Emily wanted to buy a jacket. She saw a silver jacket on sale at 25% discount and a grey jacket at 40% discount. Both jackets had the same original price before the discounts. To buy the silver jacket, Emily would need $6.40 more that what she had. So Emily bought the grey jacket. After that, she had $8 left.

1. What was the original price of the silver jacket?
2. How much money did Emily have at first?

	Silver jacket	Grey jacket
Before	100%	100%
Change	- 25%	- 40%
After	75%	60%

(a)
Difference in the discount between the silver jacket and the grey jacket
= 40% - 25%
= 15%

Additional amount that Emily needed to pay if she would buy the silver jacket
= 6.40 + 8
= $14.40

15% →  14.40
100% → ^14.40₁₅ x 100 = 96

Original price of the silver jacket = $96

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

Price of the grey jacket after discount
= ⁶⁰₁₀₀ x 96
= $57.60

Amount that Emily had at first
= 57.60 + 8
= $65.60

Answer(s): (a) $96; (b) $65.60
