Question

cost is C=2x^2+3x+10 then average cost at x=10 is​

Answer 1

SOLUTION

GIVEN

The cost is

$\displaystyle \sf{ C = 2 {x}^{2} + 3x + 10 }$

TO DETERMINE

The average cost at x = 10

EVALUATION

Here it is given that the cost is

$\displaystyle \sf{ C = 2 {x}^{2} + 3x + 10 }$

Now we have to find the average cost at x = 10

The average cost

$\displaystyle \sf{ = \frac{C}{x} }$

$\displaystyle \sf{ = \frac{2 {x}^{2} + 3x + 10}{x} }$

$\displaystyle \sf{ = 2x + 3 + \frac{ 10}{x} }$

The required average cost at x = 10

$\displaystyle \sf{ = (2 \times 10) + 3 + \frac{ 10}{10} }$

$\displaystyle \sf{ = 20 + 3 + 1}$

$\displaystyle \sf{ = 24}$
