30% of Winnie's amount was $4144 less than Will's amount. When Winnie spent 35% of her amount and Will spent 70% of his amount, they had the same amount of amount left. Find the amount that Will had at first.

	Winnie	Will
Before	60 u	130 u
Change	- 21 u	- 91 u
After	39 u	39 u

Percentage of Winnie's amount left
= 100% - 35%
= 65%

Percentage of Will's amount left
= 100% - 70%
= 30%

65% = ⁶⁵₁₀₀ = ¹³₂₀
30% = ³⁰₁₀₀ = ³₁₀

The amounts of amount that Winnie and Will had left were the same. Make the numerators the same.

¹³₂₀ of Winnie's amount = ³₁₀ of Will's amount
³⁹₆₀ of Winnie's amount = ³⁹₁₃₀ of Will's amount

Amount that Winnie had = 60 u

30% of the amount that Winnie had
= 30% x 60 u
= ³⁰₁₀₀ x 60 u
= 18 u

Difference between Will's amount and 30% of Winnie's amount
= 130 u - 18 u
= 112 u

112 u = 4144

1 u = 4144 ÷ 112 = 37

Amount that Will had at first
= 130 u
= 130 x 37
= $4810

Answer(s): $4810
