ryzh [129]

Answer:

C(x) = 5700 + 500x

Step-by-step explanation:

Total cost = fixed cost + variable cost

Fixed cost are cost that do not change in the process of production such as machineries, furnitures & fittings.

Variable cost are cost that changes with production such as cost of raw material, cost of labor.

From the question:

Fixed cost= $5,700

Cost per unit of computer = $500

If x number of computers are produced in a month

Variable cost = 500x

Total cost = fixed cost + variable cost

C(x) = 5700 + 500x

Where,

C(x) = total cost

5700= fixed cost

500x= variable cost

SCORPION-xisa [38]

Answer:

The denominator is all real numbers except 0.

Step-by-step explanation:

To find what values of x must be excluded from the domain, set the denominator equal to zero, and solve for x.

x = 0

The denominator is all real numbers except 0.
