Gwar [14]

Answer:

$C(x)= 10x-\dfrac{x^2}{20000} + 15000$

Step-by-step explanation:

Cost function (C(x)) = Fixed cost (F) + Variable cost (V(x))

Marginal cost (M(x)) = slope of Variable cost (V(x))

$V(x)=\int M(x) dx$

$V(x)=\int 10-\dfrac{x}{10000}dx$

$V(x)= 10x-\dfrac{x^2}{20000}$

Note that we do not consider the constant of integration. This constant is the fixed cost.

$C(x)= V(x) + 15000$

$C(x)= 10x-\dfrac{x^2}{20000} + 15000$
