110 Pierre's savings : Total savings = 1 : 10
Perry's savings = 20 u
20 u = 740
1 u = 740 ÷ 20 = 37
Paul's savings = 22 u
Savings of the other three boys
= 20 u + 57 u + 11 u
= 88 u
Savings that Paul had less than the total of the three other boys
= 88 u - 22 u
= 66 u
= 66 x 37
= $2442
Answer(s): $2442
