Math Problem Statement
TR = 5.000Q - 10Q² TC = 5Q²-10.000 Ditanya Q=.....? Profit maks?
Solution
To solve for the quantity that maximizes profit, we need to use the given equations for Total Revenue (TR) and Total Cost (TC), then derive the Profit function .
Step 1: Define the profit function
The profit function is defined as:
Given:
Substitute and :
Step 2: Find the critical point
To find the quantity that maximizes profit, take the derivative of with respect to , and set it equal to zero:
Solve for :
Step 3: Determine the maximum profit
Now substitute back into the profit function to find the maximum profit: Let's compute this:
Final Answer
- The quantity that maximizes profit is 166.67.
- The maximum profit is approximately 426,683.3.
