80% of Barbara's amount was $1360 more than Julian's amount. When Barbara spent 65% of her amount and Julian spent 35% of his amount, they had the same amount of amount left. Find the amount that Julian had at first.

	80% of Barbara's amount	Barbara's amount	Julian's amount
Before	208 u	260 u	140 u
Change		- 169 u (- 65%)	- 49 u (- 35%)
After		91 u	91 u

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

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

35% = ³⁵₁₀₀ = ⁷₂₀
65% = ⁶⁵₁₀₀ = ¹³₂₀

The amounts of amount that Barbara and Julian had left were the same.
Make the numerators the same.

⁷₂₀ of Barbara's amount = ¹³₂₀ of Julian's amount
⁹¹₂₆₀ of Barbara's amount = ⁹¹₁₄₀ of Julian's amount

Amount that Barbara had = 260 u

80% of the amount that Barbara had
= 260 u x 80%
= 260 u x ⁸⁰₁₀₀
= 208 u

Difference between 80% of Barbara's amount and Julian's amount
= 208 u - 140 u 
= 68 u

68 u = 1360
1 u = 1360 ÷ 68 = 20

Amount that Julian had at first
= 140 u
= 140 x 20
= $2800

Answer(s): $2800
