90% of Victoria's amount was $2322 more than Ben's amount. When Victoria spent 55% of her amount and Ben spent 35% of his amount, they had the same amount of amount left. Find the amount that Ben had at first.

	90% of Victoria's amount	Victoria's amount	Ben's amount
Before	234 u	260 u	180 u
Change		- 143 u (- 55%)	- 63 u (- 35%)
After		117 u	117 u

Percentage of Victoria's amount left
= 100% - 55%
= 45%

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

45% = ⁴⁵₁₀₀ = ⁹₂₀
65% = ⁶⁵₁₀₀ = ¹³₂₀

The amounts of amount that Victoria and Ben had left were the same.
Make the numerators the same.

⁹₂₀ of Victoria's amount = ¹³₂₀ of Ben's amount
¹¹⁷₂₆₀ of Victoria's amount = ¹¹⁷₁₈₀ of Ben's amount

Amount that Victoria had = 260 u

90% of the amount that Victoria had
= 260 u x 90%
= 260 u x ⁹⁰₁₀₀
= 234 u

Difference between 90% of Victoria's amount and Ben's amount
= 234 u - 180 u 
= 54 u

54 u = 2322
1 u = 2322 ÷ 54 = 43

Amount that Ben had at first
= 180 u
= 180 x 43
= $7740

Answer(s): $7740
