Final answer:
a. If Bob paid a commission of $40, he could buy 185 shares. b. If Bob paid a commission of $80 and used margin, he could buy 370 shares. c. Bob made a profit of $3,100 on his Verizon stock investment.
Step-by-step explanation:
To answer these questions, let's break down each scenario:
a. If Bob paid a commission of $40, he would have $3,000 - $40 = $2,960 to invest. With this amount, he can buy $2,960 / $16 = 185 shares of Verizon stock.
b. If Bob paid a commission of $80 and used his $3,000 and borrowed $3,000 on margin, he would have a total of $3,000 + $3,000 - $80 = $5,920 to invest. With this amount, he can buy $5,920 / $16 = 370 shares of Verizon stock.
c. If Bob used margin to buy his Verizon stock, paid another $40 to sell the stock, and sold the stock for $25 a share, we need to calculate the profit. He initially bought 370 shares, so his profit would be ($25 - $16) * 370 - $40 = $3,100.
