310 Tommy's savings : Total savings = 3 : 10
Ryan's savings = 30 u
30 u = 660
1 u = 660 ÷ 30 = 22
Tim's savings = 22 u
Savings of the other three boys
= 30 u + 25 u + 33 u
= 88 u
Savings that Tim had less than the total of the three other boys
= 88 u - 22 u
= 66 u
= 66 x 22
= $1452
Answer(s): $1452
