80% of Olivia's amount was $884 more than Henry's amount. When Olivia spent 65% of her amount and Henry spent 35% of his amount, they had the same amount of amount left. Find the amount that Henry had at first.

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

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

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

35% = ³⁵₁₀₀ = ⁷₂₀
65% = ⁶⁵₁₀₀ = ¹³₂₀

The amounts of amount that Olivia and Henry had left were the same.
Make the numerators the same.

⁷₂₀ of Olivia's amount = ¹³₂₀ of Henry's amount
⁹¹₂₆₀ of Olivia's amount = ⁹¹₁₄₀ of Henry's amount

Amount that Olivia had = 260 u

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

Difference between 80% of Olivia's amount and Henry's amount
= 208 u - 140 u 
= 68 u

68 u = 884
1 u = 884 ÷ 68 = 13

Amount that Henry had at first
= 140 u
= 140 x 13
= $1820

Answer(s): $1820
