15 Tommy's savings : Total savings = 1 : 5
Pierre's savings = 25 u
25 u = 450
1 u = 450 ÷ 25 = 18
Tommy's savings = 14 u
Savings of the other three boys
= 25 u + 17 u + 14 u
= 56 u
Savings that Tommy had less than the total of the three other boys
= 56 u - 14 u
= 42 u
= 42 x 18
= $756
Answer(s): $756
