110 David's savings : Total savings = 1 : 10
Caden's savings = 10 u
10 u = 110
1 u = 110 ÷ 10 = 11
David's savings = 3 u
Savings of the other three boys
= 10 u + 14 u + 3 u
= 27 u
Savings that David had less than the total of the three other boys
= 27 u - 3 u
= 24 u
= 24 x 11
= $264
Answer(s): $264
