Revenue
A small business assumes that the demand function for one of its new products can be modeled by p = cekx.
When p = $45, x = 1000 units, and when p = $40, x= 1200 units.
(a) Solve for C and k in the model.
(b) Find the values of x and p that will maximize the revenue for this product.

Answer:

Step-by-step explanation:

Given that a  small business assumes that the demand function for one of its new products can be modeled by

[tex]p=ce^{kx}[/tex]

Substitute  the given values for p and x to get two equations in c and k

[tex]40 = ce^{1200k} \\45 = ce^{1000k}[/tex]

Dividing on by other we get

[tex]\frac{45}{40} =e^{-200k} \\-200 k = ln (45/40) = 0.117583\\k = -0.000589[/tex]

Substitute value of k in any one equation

[tex]45 = ce^{-0.589} \\c=45.02651[/tex]

b) Revenue of the product is demand and price

i.e. R(x) = p*x = [tex]45.02651xe^{-0.000589x}[/tex]

Use Calculus derivative test to find max Revenue

R'(x) = [tex]45.02651 e^{-0.000589x}-45.02651*0.000589 x e^{-0.000589x}\\[/tex]

EquateI derivative to 0

1-0.000589x =0

x = 1698.037

When x = 1698 and p = 16.56469
