70% of Roshel's amount was $2576 more than Paul's amount. When Roshel spent 65% of her amount and Paul spent 10% of his amount, they had the same amount of amount left. Find the amount that Paul had at first.

	70% of Roshel's amount	Roshel's amount	Paul's amount
Before	126 u	180 u	70 u
Change		- 117 u (- 65%)	- 7 u (- 10%)
After		63 u	63 u

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

Percentage of Paul's amount left
= 100% - 10%
= 90%

35% = ³⁵₁₀₀ = ⁷₂₀
90% = ⁹⁰₁₀₀ = ⁹₁₀

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

⁷₂₀ of Roshel's amount = ⁹₁₀ of Paul's amount
⁶³₁₈₀ of Roshel's amount = ⁶³₇₀ of Paul's amount

Amount that Roshel had = 180 u

70% of the amount that Roshel had
= 180 u x 70%
= 180 u x ⁷⁰₁₀₀
= 126 u

Difference between 70% of Roshel's amount and Paul's amount
= 126 u - 70 u 
= 56 u

56 u = 2576
1 u = 2576 ÷ 56 = 46

Amount that Paul had at first
= 70 u
= 70 x 46
= $3220

Answer(s): $3220
