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

R=-1/2p^2+1900p

What unit p should be charged to maximize revenue?
What is the maximum revenue?

1900 unit p should be charged to maximise revenue and 1805000  is the maximum revenue

Step-by-step explanation:

The equation represents a parabola that is looking down and has the maximum, we have to find the vertex of equation.(p,R)

vertex =  

Here b = 1900

a =

On substituting the values

  it is your x for vertex

put it in your equation and calculate:

= -1805000 + 3610000= 1805000

price must be equal 1900 to maximise the revenue = 1805000

step-by-step explanation:

cause i just did this and got the answer

you're welcome

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
