How do I do this using my TI-83+? Please help me out.
:?

The marketing department of a company estimates that the demand for a product is given by p=104 - 0.018 x dollars, where p is the price per unit and x is the number of units.

The cost of producing x units is given by C = 570 + 80 x dollars, and the profit for producing x units is given by
P = R-C = x p - C .
Skech the graph of the profit function and estimate the number of units that would produce a maximum profit.

x for maximum
 
You can enter the profit equation in y=x(104-.018x)-(570+80x)
In window make it

1600
100
-600
850
1000

Then enter
