70% of Jaslyn's amount was $77 more than Caden's amount. When Jaslyn spent 60% of her amount and Caden spent 35% of his amount, they had the same amount of amount left. Find the amount that Caden had at first.

	70% of Jaslyn's amount	Jaslyn's amount	Caden's amount
Before	45.5 u	65 u	40 u
Change		- 39 u (- 60%)	- 14 u (- 35%)
After		26 u	26 u

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

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

40% = ⁴⁰₁₀₀ = ²₅
65% = ⁶⁵₁₀₀ = ¹³₂₀

The amounts of amount that Jaslyn and Caden had left were the same.
Make the numerators the same.

²₅ of Jaslyn's amount = ¹³₂₀ of Caden's amount
²⁶₆₅ of Jaslyn's amount = ²⁶₄₀ of Caden's amount

Amount that Jaslyn had = 65 u

70% of the amount that Jaslyn had
= 65 u x 70%
= 65 u x ⁷⁰₁₀₀
= 45.5 u

Difference between 70% of Jaslyn's amount and Caden's amount
= 45.5 u - 40 u 
= 5.5 u

5.5 u = 77
1 u = 77 ÷ 5.5 = 14

Amount that Caden had at first
= 40 u
= 40 x 14
= $560

Answer(s): $560
