With a demand curve of

Q= 80-4/3P

and average total cost of production of

ATC= 0.5Q+10+ (1,000)/Q

Which is not true?

• max total profit is positive
• max value of the total revenue function is 1200
• the profit maximizing output level is Q = 20
• The most profitable price is P= 45
• The TOTAL cost of production is TC= 0.5Q^2+10Q+1,000

Thank youu :)
