Answer:
Price per television =38.30
Step-by-step explanation:
Number of units sold in one week =230-3x
Price of one unit =x
Total money produced in one week =x(230 - 3x)
(Here it doesn't matter total money is taken for a week or day because after differentiating and equating to zero that factor disappear )
Differentiate total amount with respect to x.

Now equate it equal to zero to get extremum.
230-6x=0
Then, x = 38.30

For this case we must find a linear equation of the form:

Where,
m: slope of the line
b: cutting point with vertical axis.
For the slope we have the following equation:

Substituting values we have:

We observe that the slope of the line is not defined.
Therefore, the line is vertical.
Thus, the equation of the line is given by:

Answer:
The equation of the line is given by:
