Emma wanted to buy a jumpsuit. She saw a yellow jumpsuit on sale at 20% discount and a red jumpsuit at 40% discount. Both jumpsuits had the same original price before the discounts. To buy the yellow jumpsuit, Emma would need $4.40 more that what she had. So Emma bought the red jumpsuit. After that, she had $16 left.

1. What was the original price of the yellow jumpsuit?
2. How much money did Emma have at first?

	Yellow jumpsuit	Red jumpsuit
Before	100%	100%
Change	- 20%	- 40%
After	80%	60%

(a)
Difference in the discount between the yellow jumpsuit and the red jumpsuit
= 40% - 20%
= 20%

Additional amount that Emma needed to pay if she would buy the yellow jumpsuit
= 4.40 + 16
= $20.40

20% →  20.40
100% → ^20.40₂₀ x 100 = 102

Original price of the yellow jumpsuit = $102

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

Price of the red jumpsuit after discount
= ⁶⁰₁₀₀ x 102
= $61.20

Amount that Emma had at first
= 61.20 + 16
= $77.20

Answer(s): (a) $102; (b) $77.20
