70% of Roshel's amount was $80 more than Will's amount. When Roshel spent 55% of her amount and Will spent 35% of his amount, they had the same amount of amount left. Find the amount that Will had at first.

	70% of Roshel's amount	Roshel's amount	Will's amount
Before	182 u	260 u	180 u
Change		- 143 u (- 55%)	- 63 u (- 35%)
After		117 u	117 u

Percentage of Roshel's amount left
= 100% - 55%
= 45%

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

45% = ⁴⁵₁₀₀ = ⁹₂₀
65% = ⁶⁵₁₀₀ = ¹³₂₀

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

⁹₂₀ of Roshel's amount = ¹³₂₀ of Will's amount
¹¹⁷₂₆₀ of Roshel's amount = ¹¹⁷₁₈₀ of Will's amount

Amount that Roshel had = 260 u

70% of the amount that Roshel had
= 260 u x 70%
= 260 u x ⁷⁰₁₀₀
= 182 u

Difference between 70% of Roshel's amount and Will's amount
= 182 u - 180 u 
= 2 u

2 u = 80
1 u = 80 ÷ 2 = 40

Amount that Will had at first
= 180 u
= 180 x 40
= $7200

Answer(s): $7200
