A firm, in a perfectly competitive market, produces and sells child car seats. The sales price is $600, the fixed cost are $3,000 and the variable cost are $300 per unit. What is the marginal revenue for the 10th seat sold? Group of answer choices $480 $590 $625 $600

Joe decided to quit his computer-programming job (where he was earning $48,000 per year) to start his own software business. For his office, Joe will use a two-story building that he bought 7 years ago for $250,000. The building is located in Hyde Park (South side of Chicago) in an area where a lot of recent construction has taken place, so the market price for the land has increased. You are given the following information about the costs of his firm: Joe will pay himself a wage of: Maintenance and insurance Revenue Land's salvage (resale) value Risk-free interest rate $18,000 per year $30,240 per year $96,000 per year $395,000 4.75% annually Assume for simplicity that all taxes are equal to zero. Calculate the economicannual profits of this firm (you can assume that investing the money at the risk-free rate is its best alternative use).

Consider a firm with the market demand function for its product given by: p =1000 – 2Q; and total cost of production given by: TC = Q3 – 59Q2 + 1315Q + 2000. (a) Obtain the firm’s Total Revenue function. (b) Find the amount of Total Revenue when the firm sells 30 units of output. (c) Obtain the firm’s Profit function. (d) Find the amount of Total Profit when the firm sells 30 units of output.

Assume demand is given as P = $2500-$25Q. The firm has a fixed cost of $3000 and variable costs of $2000 +$1.50 2A. Write out the firm's total revenue equation. B. Determine the Qvalue(s) where TR = 0. Determine the Q value where TR is maximum. C. Write out the firm's total cost function. D. Determine the firm's breakeven point(s) algebraically
