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.
![\frac{dM}{dt}=230-6x](https://tex.z-dn.net/?f=%5Cfrac%7BdM%7D%7Bdt%7D%3D230-6x)
Now equate it equal to zero to get extremum.
230-6x=0
Then, x = 38.30
The reason why the trails must be in quadrant 2 or 3 is because the coordinates start with a negative number. Quadrant 2= (-,+) and quadrant 3= (-,-)
1/2 turns into 2/4 and 2/4 + 1/4 that equals 3/4 and then 11 plus 6 equals 17 3/4
