As the manager of Smith Construction, you need to make a decision on the number of homes to build in a new residential area where you are the only builder. Unfortunately, you must build the homes before you learn how strong demand is for homes in this large neighborhood. There is a 60 percent chance of low demand and a 40 percent chance of high demand. The corresponding (inverse) demand functions for these two scenarios are P = 300,000 – 400Q and P = 500,000 – 275Q, respectively. Your cost function is C(Q) = 140,000 + 240,000Q. How many new homes should you build, and what profits can you expect?

Respuesta :

The number of new houses that will be built is 200 while the profit is $13860000.

From the information given, the expected demand function will be:

= 60% × (300000 - 400Q) + 40% × (500000 - 275Q)

= 380000 - 350Q

Therefore, P = 380000 - 350Q

Since profit is the difference between the revenue and cost. This will be:

= (380000 - 350Q) × Q - (140000 + 240000Q)

Therefore, maximizing the profit will be:

380000 - 350 × 2Q - 240000 = Q

Q = 200

Therefore, profit will be:

= (380000 - 350Q) × Q - (140000 + 240000Q)

= (380000 - 350 × 200) × 200 - (140000 + 240000 × 200)

= 13,860,000
