310 Michael's savings : Total savings = 3 : 10
Valen's savings = 5 u
5 u = 175
1 u = 175 ÷ 5 = 35
Michael's savings = 9 u
Savings of the other three boys
= 5 u + 7 u + 9 u
= 21 u
Savings that Michael had less than the total of the three other boys
= 21 u - 9 u
= 12 u
= 12 x 35
= $420
Answer(s): $420
