30% of Linda's amount was $1015 less than Zane's amount. When Linda spent 30% of her amount and Zane spent 60% of his amount, they had the same amount of amount left. Find the amount that Zane had at first.

	Linda	Zane
Before	20 u	35 u
Change	- 6 u	- 21 u
After	14 u	14 u

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

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

70% = ⁷⁰₁₀₀ = ⁷₁₀
40% = ⁴⁰₁₀₀ = ²₅

The amounts of amount that Linda and Zane had left were the same. Make the numerators the same.

⁷₁₀ of Linda's amount = ²₅ of Zane's amount
¹⁴₂₀ of Linda's amount = ¹⁴₃₅ of Zane's amount

Amount that Linda had = 20 u

30% of the amount that Linda had
= 30% x 20 u
= ³⁰₁₀₀ x 20 u
= 6 u

Difference between Zane's amount and 30% of Linda's amount
= 35 u - 6 u
= 29 u

29 u = 1015

1 u = 1015 ÷ 29 = 35

Amount that Zane had at first
= 35 u
= 35 x 35
= $1225

Answer(s): $1225
