35 The amount that Flynn and Joelle each had in the end is the same. Make the numerators the same. LCM of 2 and 3 is 6.
25 of Flynn's amount =
35 of Joelle's amount
615 of Flynn's amount =
610 of Joelle's amount
Amount that Joelle had less than Flynn
= 15 u - 10 u
= 5 u
5 u = 465
1 u = 465 ÷ 5 = 93
Amount that Joelle had at first
= 10 u
= 10 x 93
= $930
