Solution
Step 1:
Find the cost per share
[tex]\begin{gathered} Cost\text{ per share = }\frac{8484.55}{400} \\ =\text{ \$21.211375} \end{gathered}[/tex]Selling price = $19.5
[tex]Total\text{ selling price = 400 }\times\text{ \$19.50 = \$7800}[/tex]a)
Amount of sale = $7800
b)
Net sale = Amount of sale - Commission
[tex]\begin{gathered} Net\text{ sale = \$7800 - \$19.95} \\ =\text{ \$7780.05} \end{gathered}[/tex]c) Amount paid = $8484.55
Net sale = $7780.05
Since net sale is less than the amount paid, hence, it is loss
Loss
