A company produces and sells hair dryers in a market where price (p) and demand (D) are related follows: p= $35 + (3,000)/D - (4,800)/D The fixed cost (C;) is $800 per month and the variable cost per hair dryer (c.) is $38. With reference to the company in Question 1, assume price and demand are unrelated. The company sells the hair dryers for $80 each if they spend $8,000 per month on advertising (C.).
