Q=80-2P
P= 40-0.5Q
MR=40-Q
Cost= 10Q
MC=dC/dQ= 10
a. No, Spanner co. is not a price taker as the firm faces a downward sloping demand curve. So Firm is price maker.
b. Profit will be maximized when MR= MC.
40-Q=10
Q*=50
P*= 40-0.5*50=15
Profit maximising price=$15
Quantity= 50.
c. Revenue maximising output: 40
Revenue= Price*Quantity= 40Q-0.5Q^2
To find the value fo Q where Revenue is maximum, Differentiate revenue with respect to Q and equate it to zero.
dTR/dQ= 40-Q=0
Q**=40
Revenue will be maximum at Q=40.
