110 Vincent's savings : Total savings = 1 : 10
Bryan's savings = 5 u
5 u = 155
1 u = 155 ÷ 5 = 31
Japheth's savings = 2 u
Savings of the other three boys
= 5 u + 11 u + 2 u
= 18 u
Savings that Japheth had less than the total of the three other boys
= 18 u - 2 u
= 16 u
= 16 x 31
= $496
Answer(s): $496
