Let A represent Alex's money.
Let P represent Paul's money.
Let C represent Collin's money.
The ratio of A to P is 7 : 10.
The ratio of P to C is 8 : 10.
The P in both ratios are the same, so:
The ratio of A to P is 28 : 40, and the ratio of P to C is 40 : 50.
Therefore, the ratio of A to P to C = 28 : 40: 50.
We know that A + C = $1755.
Since 78u = $1755, 118u = $2655.
The 3 boys have a total of $2655.
