Let's try to determine the cost function for another company like ABC who makes sausages. Assume costs are as follows:

1. Monthly depreciation on buildings and equipment is $15,047

2. Product costs are $1.92 per pound produced

3. Wages are $2.34 per pound produced

4. Supervisory Salaries total $11,184 per month

5. Utilities cost $2,251 per month plus $.20 per pound produced.

What is the variable cost portion of their cost formula? (in other words, what is the "v" in y = f + vx)

Enter your answer to two decimal places, and don't include dollar signs.
