Explanation / Answer

Let's see both scenarios if the firm does advertising and didn't do advertising. IF they do ad their sales is increased by 50% at a given cost. So at the cost of $160 total amount sold were 200 and after advertising, it will increase to 300.

If the firm does advertising its fixed cost per day will $3000. ($2000 + $1000) and the variable cost will be ($40 x 300) 12000. The total cost incurred will be $15,000. Revenue earned by the firm after selling 300 pairs of shoes at a cost of $160 will be $48,000. Net profit earned will be $48,000 - 15,000 = $33,000.

Taking another scenario into account when the firm didn't advertise, they are selling only 200 pairs of shoes at a price of $160 and making a revenue of $32,000. their cost incurred in the process will be (FC + VC) 1000 + 8000 =$9000. Total profit was $32,000 - $9,000 = $23,000.

The firm should definitely advertise.

After advertisement, they will be selling 300 pairs of shoes at a price of $160. and making a profit of $33,000.

3) They should advertise because that will increase their profit (not revenue).
