25 Billy's savings : Total savings = 2 : 5
Luke's savings = 10 u
10 u = 390
1 u = 390 ÷ 10 = 39
Paul's savings = 11 u
Savings of the other three boys
= 10 u + 12 u + 22 u
= 44 u
Savings that Paul had less than the total of the three other boys
= 44 u - 11 u
= 33 u
= 33 x 39
= $1287
Answer(s): $1287
