Brandon and Luis had some money at first. Brandon received 2 times as much money as Luis every week. At the end of 2 weeks, both of them had the same amount of money. If Luis had $1200 at first and Brandon had $2300 at the end of those 2 weeks, what is the ratio of Brandon's money to the total amount of money at first?

+ 2 u |
+ 1 u |

$2300 |
$2300 |
Amount that Luis received every week
= 2300 - 1200
= $1100
1 u = 1100
Amount that Brandon received every week
= 2 u
= 2 x 1100
= $2200
Amount that Brandon had at first
= 2300 - 2200
= $100
Total amount that Brandon and Luis had at first
= 1200 + 100
= $1300
Brandon's amount : Total amount
100 : 1300
1 : 13
Answer(s): 1 : 13
