Hi,

I hope someone can help. I'm currently working on 10c:

I know that the equation for the function is (25+x)(20,000-750x). In terms of finding the point of maximum revenue, I'm finding a hard time doing so. When I plot this on a graph, I get very large values. The answer according to the textbook is $25.83.

Can someone help identify with me where the maximum point is for this equation?

Thanks,

Olivia
