310 Vincent's savings : Total savings = 3 : 10
Valen's savings = 20 u
20 u = 660
1 u = 660 ÷ 20 = 33
Vincent's savings = 21 u
Savings of the other three boys
= 20 u + 15 u + 14 u
= 49 u
Savings that Vincent had less than the total of the three other boys
= 49 u - 21 u
= 28 u
= 28 x 33
= $924
Answer(s): $924
