310 Brandon's savings : Total savings = 3 : 10
Glen's savings = 10 u
10 u = 210
1 u = 210 ÷ 10 = 21
Brandon's savings = 9 u
Savings of the other three boys
= 10 u + 8 u + 3 u
= 21 u
Savings that Brandon had less than the total of the three other boys
= 21 u - 9 u
= 12 u
= 12 x 21
= $252
Answer(s): $252
