Question

The John Deere company has found that the revenue from sales of heavy-duty tractors is a function of the unit price p that it charges. The revenue R is given by the following function.

R(p)= (-1/2)p^2+1520p

What unit price p should be charged to maximize revenue? Give your answer correct to the nearest dollar. ...?

Answer 1

Well what you need to have in mind is that when we use this data like this:
−b/2a in this case you get 1520 / 1=1520
Then what you need to do is plug 1520 into the revenue function which is
R(p)= (-1/2)p^2+1520p
With that you will get to the answer. I hope this can help you through
