15 Tommy's savings : Total savings = 1 : 5
George's savings = 15 u
15 u = 390
1 u = 390 ÷ 15 = 26
Tommy's savings = 11 u
Savings of the other three boys
= 15 u + 18 u + 11 u
= 44 u
Savings that Tommy had less than the total of the three other boys
= 44 u - 11 u
= 33 u
= 33 x 26
= $858
Answer(s): $858
