110 Japheth's savings : Total savings = 1 : 10
Michael's savings = 5 u
5 u = 130
1 u = 130 ÷ 5 = 26
Xavier's savings = 6 u
Savings of the other three boys
= 5 u + 16 u + 3 u
= 24 u
Savings that Xavier had less than the total of the three other boys
= 24 u - 6 u
= 18 u
= 18 x 26
= $468
Answer(s): $468
