50% of Kimberly's amount was $650 less than George's amount. When Kimberly spent 30% of her amount and George spent 60% of his amount, they had the same amount of amount left. Find the amount that George had at first.

	Kimberly	George
Before	20 u	35 u
Change	- 6 u	- 21 u
After	14 u	14 u

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

Percentage of George's amount left
= 100% - 60%
= 40%

70% = ⁷⁰₁₀₀ = ⁷₁₀
40% = ⁴⁰₁₀₀ = ²₅

The amounts of amount that Kimberly and George had left were the same. Make the numerators the same.

⁷₁₀ of Kimberly's amount = ²₅ of George's amount
¹⁴₂₀ of Kimberly's amount = ¹⁴₃₅ of George's amount

Amount that Kimberly had = 20 u

50% of the amount that Kimberly had
= 50% x 20 u
= ⁵⁰₁₀₀ x 20 u
= 10 u

Difference between George's amount and 50% of Kimberly's amount
= 35 u - 10 u
= 25 u

25 u = 650

1 u = 650 ÷ 25 = 26

Amount that George had at first
= 35 u
= 35 x 26
= $910

Answer(s): $910
