Alice has £85 and Scott has £67.
Total money = 85+67
= 152
The ratio that we want to divide the money = 3:1
Money that Alice will have = 3x
Money that Scott will have = x
[tex]3x + x = 152 \\ 4x = 152 \\ x = \frac{152}{4} \\ \\ x = 38[/tex]
Scott has 67
67-38 = 29
Answer = 29
He should give Alice 29 so that Alice has 3 times as much money as Scott
Hope this will help....
