Sal’s satellite company broadcasts TV to subscribers in Los Angeles and New York. The demand functions for each of these two groups are

QNY =150−0.75PNY QLA=80−0.25PLA

where Q is in thousands of subscriptions per year and P is the subscription price per year. The cost of providing Q units of service is given by C = 1000 + 40Q where Q = QNY + QLA

What are the profit-maximizing price and quantity for Los Angeles?

Homework Answers

Answer #1

Since there is only one broadcaster, he will maximize the joint profit

profit = PNY*QNY + PLA*QLA - C

to maximize the profit, we will partially differentiate profit first w.r.t QNY and then w.r.t QLA

and set it equal to zero.

the calculation below:---

Hence the profit-maximizing QLA = 35 &

profit-maximizing PLA = $180
