Math Problem Statement
Suppose a company has fixed costs of $1800 and variable costs per unit of 15/16x + 1110 dollars, where x is the total number of units produced. Suppose further that the selling price of its product is 1200- 1/16x dollars per unit. Find the maximum revenue.
Solution
The revenue for a company is calculated as the selling price per unit multiplied by the number of units sold. The problem gives the selling price per unit as:
Thus, the total revenue function is:
Expanding this, we get:
Now, to find the maximum revenue, we need to find the critical points by taking the derivative of and setting it equal to zero.
Step 1: Differentiate the revenue function
Step 2: Set to find the critical points
Solving for :
Step 3: Verify that this critical point is a maximum by using the second derivative test
The second derivative of is:
Since is negative, the function is concave down at , indicating that this is a maximum point.
Step 4: Calculate the maximum revenue
Substitute into the revenue function:
Now calculating:
Thus, the maximum revenue is $5,760,000.
