### different demand functions that have the same cost function

I need to know how to calculate demand and price for two different demand functions that have the same cost function. P1 = 20 - .0125Q1 P2 = 40 - .025Q2 ATC = MC = 3.00. How do I calculate the price and quantity for each? How does ATC/MC factor into the price/quantity estimate? What is the economic profit for each?

### Follow-Up Question Regarding Solving for Price and Quantity

For monopoly set the price when MC=MR For calculating MR first write the equation for total revenue (TR) TR=P*Q = (800-5Q)*Q --------(1) Differentiate (1) w.r.t. Q to get MR MR=dTR/dQ = 800 - 10Q----------(2) MC = 15Q Equate MC and MR, we get Q = 32 Put this in equation for P to calculate P, P=640 The above resp

Some tennis clubs charge an up-front fee to join and a per-hour charge for court time. Others do not charge a membership fee but charge a higher per-hour fee for court time. Consider clubs in two different locations. One is located in a suburban area where the residents tend to be of similar age, income, and occupation. Whic

### Economics for Water Projects

Suppose there is a water project, in where \$100,000,000 has been spent. Additional cost is needed is \$200,000,000. When completed the project will yield total \$150,000,000. There is an argument when the project should completed. Otherwise the first \$100,000,000 will have been wasted. What comment and recommendation is needed fo

### Marginal Revenue - Marginal Cost

If a firm finds out that its MR is greater than its MC, it should: a) increase production and sales B0 decrease production and sales c) encourage the entry of other firms into the market d) keep raising its selling price until MR =MC. E) change nothing because profits are maximized.

### Marginal Revenue - Demand Curves

Marginal Revenue becomes negative for a firm faced with a downward-sloping demand curve when: a) the demand price becomes negative b) the demand elasticity drops from elastic to inelastic c) total revenue is maximized d) the loss on previous units is at is maximum e) both b and c
