Chapter 6: Q. 77 (page 698)

A manufacturer of stereo sound speakers has found that the revenue received from selling the speakers at a cost of p dollars each is given by the polynomial $- 4 p^{2} + 420 p$ . Find the revenue received when $p = 60$ dollars

Short Answer

Expert verified

The revenue received when $p = 60$ dollars is $10800.

Step by step solution

Step 1. Given information.

The revenue received from selling the speakers at a cost of p dollars each is:

$- 4 p^{2} + 420 p$

The cost of each speaker is $p = 60$ dollars.

Step 2. Evaluate the expression for the given value.

Substitute $p = 60$ in the given expression.

$\begin{array}{rcl} - 4 (60)^{2} + 420 (60) & = & - 4 (3600) + 25200 \\ = & - 14400 + 25200 \\ = & 10800 \end{array}$

Step 3. Conclusion.

The revenue received when $p = 60$ dollars is $10800
