Answer:
The profit is 75
Step-by-step explanation:
The price at which the shares were bought is:
[tex]31 \frac{1}{2}=31+\frac{1}{2} = 31.5[/tex]
The price at which it will sell the shares is:
[tex]35 \frac{1}{4}=35+\frac{1}{4} = 35.25[/tex]
The number of shares that will be sold is:
[tex]n=20[/tex]
So the profit is:
[tex]Profit = n(35.25 - 31.5)\\\\Profit=20(3.75)\\\\Profit=75[/tex]
