Eric and Oliver had some money at first. Eric received 2 times as much money as Oliver every day. At the end of 6 days, both of them had the same amount of money. If Oliver had $1100 at first and Eric had $1700 at the end of those 6 days, what is the ratio of Eric's money to the total amount of money at first?

+ 2 u |
+ 1 u |

$1700 |
$1700 |
Amount that Oliver received every day
= 1700 - 1100
= $600
1 u = 600
Amount that Eric received every day
= 2 u
= 2 x 600
= $1200
Amount that Eric had at first
= 1700 - 1200
= $500
Total amount that Eric and Oliver had at first
= 1100 + 500
= $1600
Eric's amount : Total amount
500 : 1600
5 : 16
Answer(s): 5 : 16
