35 The amount that Will and Eva each had in the end is the same. Make the numerators the same. LCM of 2 and 3 is 6.
25 of Will's amount =
35 of Eva's amount
615 of Will's amount =
610 of Eva's amount
Amount that Eva had less than Will
= 15 u - 10 u
= 5 u
5 u = 375
1 u = 375 ÷ 5 = 75
Amount that Eva had at first
= 10 u
= 10 x 75
= $750
Answer(s): $750
