310 Michael's savings : Total savings = 3 : 10
Fabian's savings = 15 u
15 u = 540
1 u = 540 ÷ 15 = 36
Michael's savings = 12 u
Savings of the other three boys
= 15 u + 9 u + 4 u
= 28 u
Savings that Michael had less than the total of the three other boys
= 28 u - 12 u
= 16 u
= 16 x 36
= $576
Answer(s): $576
