Percentage of Lucy's amount left
= 100% - 25%
= 75%
Percentage of Flynn's amount left
= 100% - 60%
= 40%
75% =
75100 =
34 40% =
40100 =
25 The amounts of amount that Lucy and Flynn had left were the same. Make the numerators the same.
34 of Lucy's amount =
25 of Flynn's amount
68 of Lucy's amount =
615 of Flynn's amount
Amount that Lucy had = 8 u
40% of the amount that Lucy had
= 40% x 8 u
=
40100 x 8 u
= 3.2 u
Difference between Flynn's amount and 40% of Lucy's amount
= 15 u - 3.2 u
= 11.8 u
11.8 u = 413
1 u = 413 ÷ 11.8 = 35
Amount that Flynn had at first
= 15 u
= 15 x 35
= $525
Answer(s): $525
