If tim does not buy def, how much can he spend on abc? how many shares of abc can he buy if he does not buy def (nearest tenth)? if the selling price is $2,100, how much will tim have earned by investing if he did not buy def? what is the cash to tim divided by the total cost in this example (nearest 1%), if he did not buy def?

Given that 100 shares of ABC costs $425 and 100 shares of DEF costs $600 with a $375 commission.

Part A:

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:

Given that 100 shares of ABC costs $425, then 1 share of ABC costs $425 / 100 = $4.25.

From part A, we have that Tim has $1,400 to spend on ABC if he does not buy DEF.

Thus, If Tim does not buy DEF, he can buy $1,400 / $4.25 = 329.4 shares of ABC.

Therefore, Tim  can buy 329.4 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.

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, 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, the cash to Tim divided by the total cost in this example to the (nearest 1%), if he did not buy DEF is 150%
