310 Howard's savings : Total savings = 3 : 10
Rael's savings = 15 u
15 u = 180
1 u = 180 ÷ 15 = 12
Henry's savings = 12 u
Savings of the other three boys
= 15 u + 1 u + 12 u
= 28 u
Savings that Henry had less than the total of the three other boys
= 28 u - 12 u
= 16 u
= 16 x 12
= $192
Answer(s): $192
