310 Tom's savings : Total savings = 3 : 10
Seth's savings = 30 u
30 u = 450
1 u = 450 ÷ 30 = 15
Reggie's savings = 7 u
Savings of the other three boys
= 30 u + 12 u + 21 u
= 63 u
Savings that Reggie had less than the total of the three other boys
= 63 u - 7 u
= 56 u
= 56 x 15
= $840
Answer(s): $840
