If fixed cost of 20 articles is RS. 500 and variable cost for each additional article is RS 50. Find the total cost functions. Also find the total cost of 100 articles.

Function is " S = F + v * x ".

The total cost of 100 article is Rs 5500.

Step-by-step explanation:

The fixed cost (F) = Rs 500.

The variable cost of each article (v) = Rs 50.

let the number of article is denoted by ' x '.

The total cost function (S) is given by

S = F + v * x

Now we have to calculate the total cost of 100 article.

F = Rs 500.

v = Rs 50.

x = 100

S = 500 + 100 * 50 = Rs 5500
