310 Daniel's savings : Total savings = 3 : 10
Billy's savings = 20 u
20 u = 700
1 u = 700 ÷ 20 = 35
Bobby's savings = 11 u
Savings of the other three boys
= 20 u + 46 u + 33 u
= 99 u
Savings that Bobby had less than the total of the three other boys
= 99 u - 11 u
= 88 u
= 88 x 35
= $3080
Answer(s): $3080
