310 Fabian's savings : Total savings = 3 : 10
Justin's savings = 5 u
5 u = 150
1 u = 150 ÷ 5 = 30
Jeremy's savings = 8 u
Savings of the other three boys
= 5 u + 15 u + 12 u
= 32 u
Savings that Jeremy had less than the total of the three other boys
= 32 u - 8 u
= 24 u
= 24 x 30
= $720
Answer(s): $720
