110 Howard's savings : Total savings = 1 : 10
Glen's savings = 20 u
20 u = 400
1 u = 400 ÷ 20 = 20
Bryan's savings = 36 u
Savings of the other three boys
= 20 u + 25 u + 9 u
= 54 u
Savings that Bryan had less than the total of the three other boys
= 54 u - 36 u
= 18 u
= 18 x 20
= $360
Answer(s): $360
