$1950 |
Amount that Tommy received every month
= 1950 - 1150
= $800
1 u = 800
Amount that Michael received every month
= 2 u
= 2 x 800
= $1600
Amount that Michael had at first
= 1950 - 1600
= $350
Total amount that Michael and Tommy had at first
= 1150 + 350
= $1500
Michael's amount : Total amount
350 : 1500
7 : 30
Answer(s): 7 : 30
