40% of Xandra's amount was $882 less than Mark's amount. When Xandra spent 35% of her amount and Mark spent 60% of his amount, they had the same amount of amount left. Find the amount that Mark had at first.

	Xandra	Mark
Before	40 u	65 u
Change	- 14 u	- 39 u
After	26 u	26 u

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

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

65% = ⁶⁵₁₀₀ = ¹³₂₀
40% = ⁴⁰₁₀₀ = ²₅

The amounts of amount that Xandra and Mark had left were the same. Make the numerators the same.

¹³₂₀ of Xandra's amount = ²₅ of Mark's amount
²⁶₄₀ of Xandra's amount = ²⁶₆₅ of Mark's amount

Amount that Xandra had = 40 u

40% of the amount that Xandra had
= 40% x 40 u
= ⁴⁰₁₀₀ x 40 u
= 16 u

Difference between Mark's amount and 40% of Xandra's amount
= 65 u - 16 u
= 49 u

49 u = 882

1 u = 882 ÷ 49 = 18

Amount that Mark had at first
= 65 u
= 65 x 18
= $1170

Answer(s): $1170
