70% of Penelope's amount was $473 more than Lee's amount. When Penelope spent 55% of her amount and Lee spent 20% of his amount, they had the same amount of amount left. Find the amount that Lee had at first.

	70% of Penelope's amount	Penelope's amount	Lee's amount
Before	56 u	80 u	45 u
Change		- 44 u (- 55%)	- 9 u (- 20%)
After		36 u	36 u

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

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

45% = ⁴⁵₁₀₀ = ⁹₂₀
80% = ⁸⁰₁₀₀ = ⁴₅

The amounts of amount that Penelope and Lee had left were the same.
Make the numerators the same.

⁹₂₀ of Penelope's amount = ⁴₅ of Lee's amount
³⁶₈₀ of Penelope's amount = ³⁶₄₅ of Lee's amount

Amount that Penelope had = 80 u

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

Difference between 70% of Penelope's amount and Lee's amount
= 56 u - 45 u 
= 11 u

11 u = 473
1 u = 473 ÷ 11 = 43

Amount that Lee had at first
= 45 u
= 45 x 43
= $1935

Answer(s): $1935
