Tommy and Bobby had some money at first. Tommy received 2 times as much money as Bobby every day. At the end of 4 days, both of them had the same amount of money. If Bobby had $1250 at first and Tommy had $2250 at the end of those 4 days, what is the ratio of Tommy's money to the total amount of money at first?

$2250 |
Amount that Bobby received every day
= 2250 - 1250
= $1000
1 u = 1000
Amount that Tommy received every day
= 2 u
= 2 x 1000
= $2000
Amount that Tommy had at first
= 2250 - 2000
= $250
Total amount that Tommy and Bobby had at first
= 1250 + 250
= $1500
Tommy's amount : Total amount
250 : 1500
1 : 6
Answer(s): 1 : 6
