A company that manufactures bicycles has a fixed cost of $80,000. It costs $200 to produce each bicycle. The

total cost for the company is the sum of its fixed cost and variable costs. Write the total cost, C, as a function of
the number of bicycles produced, x. Then, find and interpret C(110).
The total cost function is C(x) =

To write the total cost \( C \) as a function of the number of bicycles produced \( x \), we start by noting that the total cost consists of fixed costs and variable costs.

  1. Fixed Costs: The fixed cost is a constant amount that does not change with the number of bicycles produced. In this case, the fixed cost is $80,000.

  2. Variable Costs: The variable cost is the cost per unit produced multiplied by the number of units produced. Here, it costs $200 to produce each bicycle. Therefore, the variable cost for \( x \) bicycles is \( 200x \).

The total cost \( C(x) \) can be expressed as the sum of the fixed cost and the variable cost:

\[ C(x) = \text{Fixed Costs} + \text{Variable Costs} = 80,000 + 200x \]

So the total cost function is:

\[ C(x) = 80,000 + 200x \]

Next, we need to find \( C(110) \):

\[ C(110) = 80,000 + 200(110) \]

Calculating \( 200(110) \):

\[ 200 \times 110 = 22,000 \]

Now substitute back into the equation:

\[ C(110) = 80,000 + 22,000 = 102,000 \]

Interpretation of \( C(110) \)

The value \( C(110) = 102,000 \) indicates that the total cost of producing 110 bicycles is $102,000. This includes both the fixed costs and the variable costs associated with making those bicycles.
