Question 48191: I need a little help with this one please:
Maximizing profit. The total profit (in dollars) for sales of �x� rowing machines is given by P(x) = -0.2x� + 300x � 200.
What is the profit if 500 are sold?

For what value of �x� will the profit be at a maximum?

Thanks

P(x) = -0.2x� + 300x � 200 Realize that x=500 and then substitue it in to the function so
P(500)=-0.2(500)� + 300(500) � 200
I'll let you do the rest as I am without my calculator at the moment. Please let me know if you need more help with this problem
