Given that 100 shares of ABC costs $425 and 100 shares of DEF costs $600 with a $375 commission.
Part A:
<span>If Tim does not buy DEF, then he has $425 + $600 + $375 = $1,400 to spend on ABC.
Therefore, Tim has $1,400 to spend on ABC if he does not buy DEF.
Part B:
</span><span>Given that 100 shares of ABC costs $425, then 1 share of ABC costs $425 / 100 = $4.25.
From part A, we have that </span>Tim has $1,400 to spend on ABC if he does not buy DEF.
Thus, I<span>f Tim does not buy DEF, he can buy $1,400 / $4.25 = 329.4 shares of ABC.
Therefore, Tim </span>can buy 329.4 <span>shares of ABC if he does not buy DEF.
Part C:
Given that Tim spent $1,400 to buy shares of ABC when he did not buy DEF. </span> <span> If the selling price is $2,100, Tim will have earned $2,100 - $1,400 = $700 by investing if he did not buy DEF
Therefore, </span><span>If the selling price is $2,100, Tim will have earned $700 by investing if he did not buy DEF.
Part D:
Given that the selling price is $2,100 and the cost price is $1,400, then the cash to Tim divided by the total cost, if he did not buy DEF is given by $2,100 / $1,400 = 1.5 = 150%
Therefore, </span><span>the cash to Tim divided by the total cost in this example to the (nearest 1%), if he did not buy DEF</span> is 150%
