70% of Erika's amount was $567 more than Paul's amount. When Erika spent 65% of her amount and Paul spent 20% of his amount, they had the same amount of amount left. Find the amount that Paul had at first.

	70% of Erika's amount	Erika's amount	Paul's amount
Before	56 u	80 u	35 u
Change		- 52 u (- 65%)	- 7 u (- 20%)
After		28 u	28 u

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

Percentage of Paul's amount left
= 100% - 20%
= 80%

35% = ³⁵₁₀₀ = ⁷₂₀
80% = ⁸⁰₁₀₀ = ⁴₅

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

⁷₂₀ of Erika's amount = ⁴₅ of Paul's amount
²⁸₈₀ of Erika's amount = ²⁸₃₅ of Paul's amount

Amount that Erika had = 80 u

70% of the amount that Erika had
= 80 u x 70%
= 80 u x ⁷⁰₁₀₀
= 56 u

Difference between 70% of Erika's amount and Paul's amount
= 56 u - 35 u 
= 21 u

21 u = 567
1 u = 567 ÷ 21 = 27

Amount that Paul had at first
= 35 u
= 35 x 27
= $945

Answer(s): $945
