The expense function for a widget is E = -3,000p + 250,000. The revenue function is R = -600p^2 + 25,000p. Write the profit equation in simplified form ( P= R- E) . Use the axis of symmetry formula to determine the maximum profit price and the maximum profit.

Respuesta :

The equation of profit will be P = -600p² + 28,000p - 250,000. Then the maximum profit is $ 76,667 at a maximum profit price $ 23.33.

What is a profit?

A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running or creating anything.

The expense function for a widget is E = -3,000p + 250,000.

The revenue function is R = -600p² + 25,000p.

Then the profit equation is in simplified form (P =  R- E).

P = (-600p² + 25,000p) - (-3,000p + 250,000)

P = -600p² + 25,000p + 3,000p - 250,000

P = -600p² + 28,000p - 250,000

Then the maximum profit will be

Differentiate P with respect to p, then we have

P' = -1,200p + 28,000

For maximum profit P" < 0, P' = 0. Then we have

P" = -1,200

P" < 0

Then we have

                         P' = 0

-1,200p + 28,000 = 0

                 1,200p = 28,000

                          p = 23.33

Then the profit will be

P = -600(23.33)² + 28,000(23.33) - 250,000

P = -326,573.34 + 653,240 - 250,000

P = 76,666.67

P ≅ 76,667
