110 Ian's savings : Total savings = 1 : 10
Billy's savings = 40 u
40 u = 760
1 u = 760 ÷ 40 = 19
Glen's savings = 22 u
Savings of the other three boys
= 40 u + 37 u + 11 u
= 88 u
Savings that Glen had less than the total of the three other boys
= 88 u - 22 u
= 66 u
= 66 x 19
= $1254
Answer(s): $1254
