Here's the problem:
An economist for a sporting goods company estimates the revenue and cost functions for the production of a new snowboard. These functions are and , respectively, where x is the number of snowboards produced, in thousands. The average profit is defined by the function AP(x) = P(x) / x , where P(x) is the profit function. Determine the production levels that make AP(x) > 0
What i did is :
Is this the right inequality to solve the problem?
