Chapter 1.3, Problem 53E

How do you find the value of a function?

An outpatient operating room charges each patient a fixed amount per surgery plus an amount per minute for use. One patient was charged 250 for a 30-minute surgery and another patient was charged 450 for a 90-minute surgery. Determine the linear function that would be used to compute the charges. Use the function to determine the charge when a patient has a 45-minute surgery.

Explain how to find the output variable in a wordp roblem that uses a linear function.
