A manufacturer produces televisions. He estimates that by selling them for x dollars each, he will be able to sell 230 – 3x each
poizon [28]

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

Now equate it equal to zero to get extremum.

230-6x=0

Then, x = 38.30

The function f(x)=70n -400 models the profit of the instructor of a guitar class per month, where n is the number of students en
suter [353]
Given:
f(x) = 70n - 400   : equation for monthly profit.
n = number of students enrolled in the guitar class.

70 refers to the amount charged per student.
400 is the fixed expense made by the instructor.

For the instructor to have a profit, the product of 70n must be more than 400.

400/70 = 5.7 or 6

There must be at least 6 students enrolled in class for the instructor to generate profit.

f(x) = 70(6) - 400 = 420 - 400 = 20

1000 = 70n - 400
1000 + 400 = 70n
1400 = 70n
1400/70 = n
20 = n

There must be 20 students enrolled in class for the instructor to earn 1000 in profit.

1000 = 70(20) - 400
1000 = 1400 - 400
1000 = 1000
