### Cost, revenue, and profit functions.

"A Company has a fixed cost of \$20,000 and a production cost of \$8 for each unit it manufactures. A unit sells for \$10."

a) What is the cost function?

b) What is the revenue function?

c) What is the profit function?

d) Compute the profit (loss) corresponding to production levels of 7,000, 9,000 and 12,000 units, respectively.

Thanks so much

a) What is the cost function?

If they make 1 unit, what is the variable cost?

If they make 2 units, what is the variable cost?

If they make 3 units, what is the variable cost?

If they make x units, what is the variable cost?

Since the total cost is the fixed cost plug the variable cost, what function represents the cost C(x) for x units?

If they sell 1 unit, what is the revenue?

If they sell 2 units, what is the revenue?

If they sell 3 units, what is the revenue?

If they sell x units, what is the revenue?

What then is the function for the revenue R(x) from x units?

kittykat616 wrote:c) What is the profit function?

Since profit is the difference between revenue and cost, what function represents the profit P(x) for x units?

Plug the given x-values into your formula for P(x). Simplify to find the required values.
