25Bobby and Cindy had the same amount of money in the end. Make the numerators the same. LCM of 5 and 2 is 10.
56 of Cindy's money =
25 of Bobby's money
1012 of Cindy's money =
1025 of Bobby's money
Amount that Cindy had at first = 12 u
Amount that Bobby had at first = 25 u
Amount that Cindy had less than Bobby had at first
= 25 u - 12 u
= 13 u
13 u = 1196
1 u = 1196 ÷ 13 = 92
Amount that Bobby had at first
= 25 u
= 25 x 92
= $2300
Answer(s): $2300
