Answer:
a) R(p) = 320p - 0.15p²
b) P = $1066.67
c) Revenue = $170666.67
Explanation:
We know that the demand Q is given by
Q = 320 - 0.15p
Then, the revenue R is equal to P*Q, so by replacing the expression above, we get
R(p) = p*Q
R(p) = p(320 - 0.15p)
R(p) = 320p - 0.15p²
Now, to find the price that maximizes the revenue, we need to find the coordinate of the vertex of a parabola. This coordinate is equal to -b/2a, where b is the number besides p and a is the number beside p². So, the price that maximizes revenue is
[tex]\begin{gathered} p=\frac{-b}{2a} \\ \\ p=\frac{-320}{2(-0.15)}=1066.67 \end{gathered}[/tex]Finally, to know the maximum revenue, we need to replace p = 1066.67 on the equation for R(p).
[tex]\begin{gathered} R(p)=320p-0.15p^2 \\ R(p)=320(1066.67)-0.15(1066.67)^2 \\ R(p)=170666.67 \end{gathered}[/tex]Therefore, the answers are
a) R(p) = 320p - 0.15p²
b) P = $1066.67
c) Revenue = $170666.67
