310 Bobby's savings : Total savings = 3 : 10
Owen's savings = 25 u
25 u = 350
1 u = 350 ÷ 25 = 14
Bobby's savings = 24 u
Savings of the other three boys
= 25 u + 23 u + 8 u
= 56 u
Savings that Bobby had less than the total of the three other boys
= 56 u - 24 u
= 32 u
= 32 x 14
= $448
Answer(s): $448
