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

Before you use the quadratic formula, you have to make sure the equation itself is a quadratic and that a and b are not 0.
If you would like to find the numerator of a fraction, you can do this using the following steps:
denominator ... 6 * 5 = 30
numerator ... x = ?
36 = numerator / denominator
36 = x / 30
x = 36 * 30
x = 1080
The correct result would be 1080.
