Suppose a nonlinear price discriminating monopolist faces an inverse demand​ curve: P = 175 - Q​
and can set three prices depending on the quantity a consumer purchases. The​ firm's profit​ is: ​
pi = P1 Q1 + P2 (Q2 - Q1) + P3 (Q3 - Q2) - mQ3
where p1 is the high price charged on the first units Q1 ​(first block) and p2 is a lower price charged on the next (Q1 - Q2) units and is the lowest price charged on the remaining (Q3 - Q2) units. Q3 is the total number of units actually​ purchased, and m ​= ​$50 is the​ firm's constant marginal and average cost. Using​ calculus, determine the​ profit-maximizing values for p1, p2​, and p3​, and the​ firm's profits.

What are two benefits of consumer programs

You are the manager of a large crude-oil refinery. as part of the refining process, a certain heat exchanger (operated at high temperatures and with abrasive material flowing through it) must be replaced every year. the replacement and downtime cost in the first year is $165 comma 000. this cost is expected to increase due to inflation at a rate of 7% per year for six years (i.e. until the eoy 7), at which time this particular heat exchanger will no longer be needed. if the company's cost of capital is 15% per year, how much could you afford to spend for a higher quality heat exchanger so that these annual replacement and downtime costs could be eliminated?
