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.
[tex]\frac{dM}{dt}=230-6x[/tex]
Now equate it equal to zero to get extremum.
230-6x=0
Then, x = 38.30
