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) = -0.2x² + 300x – 200.
What is the profit if 500 are sold?

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


Thanks

You can put this solution on YOUR website!
P(x) = -0.2x² + 300x – 200 Realize that x=500 and then substitue it in to the function so
P(500)=-0.2(500)² + 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
