Answer:
[tex]-0.0002x^2 +26x-120000[/tex]
Step-by-step explanation:
The correct question should be:
We have been told that all we have to do to get profit is to subtract the cost from revenue.
Revenue = [tex]40x - 0.0002x^2[/tex]
Cost = [tex]14x + 120,000[/tex]
Hence:
Profit = [tex]40x - 0.0002x^2 - (14x + 120000)[/tex]
[tex]40x - 0.0002x^2 - 14x - 120000\\\\40x - 14x - 0.0002x^2 - 120000\\\\26x - 0.0002x^2 - 120000[/tex]
Putting it in ordered form:
[tex]-0.0002x^2 +26x-120000[/tex]
This is an expression for the profit.
