The total cost of producing a type of truck is given by [tex]C(x) = 10000 - 80x + 0.2x^2[/tex], where [tex]x[/tex] is the number of trucks produced. How many trucks should be produced to incur the minimum cost?

Answer :

Final answer:

To incur minimum cost, 1000 trucks should be produced.

Explanation:

To find the number of trucks that should be produced to incur minimum cost, we need to determine the minimum point of the cost function C(x) = 10000 - 80x + 0.2x².

The minimum point of a quadratic function can be found using the formula x = -b/(2a), where a and b are the coefficients of x² and x, respectively.

In this case, a = 0.2 and b = -80. Plugging these values into the formula, we get:

x = -(-80)/(2(0.2)) = 400/0.4 = 1000.

Therefore, the minimum cost would be incurred when 1000 trucks are produced.
