It is given that 50 bonds were bought with a cost of $1000 each.
6.5% brokerage was paid.
The total price of the share without brokerage is:
[tex]C=50\times1000\times\frac{99.75}{100}=49875[/tex]The brokerage is given by:
[tex]B=49875\times\frac{6.5}{100}=3241.88[/tex]Hence the total cost of the sale is given by:
[tex]\begin{gathered} T=C+B \\ T=49875+3241.88 \\ T=53116.88 \end{gathered}[/tex]Hence the total cost of sale is $53116.88.
