Write a linear cost function for the situation. identify all variables used. a parking garage charges 4 dollars plus 65 cents per half-hour. a linear cost function for the situation is c(x)=l (use integers or decimals for any numbers in the expression)

The linear cost function is dollar.

Step-by-step explanation:

Given : A parking garage charges 4 dollars plus 65 cents per half-hour. A linear cost function for the situation is C(x)=L.

To find : Write a linear cost function for the situation ?

Solution :

Cost function is defined as sum of marginal cost and fixed cost.

Let x be the number of hours i.e. time for which parking cost.

A parking garage charges 4 dollars plus 65 cents per half-hour.

The fixed price is $4.

Marginal cost is 65 cents per half-hour.

Converting cents into dollar,

1 cent = 0.01 dollar

65 cent = 0.65 dollar

The cost of hour = $0.65

The cost of x hours =

So, marginal cost is $1.3x.

Cost function is defined as

dollar.

Therefore, The linear cost function is dollar where x is the number of hours.
