If the marginal revenue (in dollars per unit) for a month is given by MR = −0.5x + 400, what is the total revenue from the produ

Vesna [10]

Given:

Marginal revenue (in dollars per unit) for a month is

$MR=-0.5x+400$

To find:

The total revenue from the production and sale of 30 units.

Solution:

We know that, total revenue is integration of marginal revenue with respect to quantity.

$TR=\int MR dx$

$TR=\int (-0.5x+400) dx$

$TR=-0.5\int x dx+400\int 1 dx$

$TR=-0.5\times \dfrac{x^2}{2}+400x$

Now, substitute x=30 in the equation of Total Revenue (TR).

$TR=-0.5\times \dfrac{30^2}{2}+400(30)$

$TR=-0.5\times \dfrac{900}{2}+12000$

$TR=-225+12000$

$TR=11775$

Therefore, the total revenue from the production and sale of 30 units is $11,775.

Limits of a Function

Novay_Z [31]

We are given the equation:

$\lim_{x \to 1} \frac{f(x)-8}{x-1} = 10$

which can be rewritten as:

$\frac{\lim_{x \to 1}[f(x)-8]}{\lim_{x \to 1}[x-1]} = 10$

$\lim_{x \to 1}[f(x)-8] = 10*\lim_{x \to 1}[x-1]$

$\lim_{x \to 1}[f(x)-8] = \lim_{x \to 1}[10x-10]$

which means that..

$f(x) - 8 = 10x - 10$

$f(x) = 10x - 10 + 8$

$f(x) = 10x - 2$

Finding the limit:

 $\lim_{x \to 1} f(x) = \lim_{x \to 1} (10x - 2)$ 

 $\lim_{x \to 1} f(x) = 10(1) - 2$ 

 $\lim_{x \to 1} f(x) = 8$
