how would i write a equation if the company charges $38 for a house call and $26 per hour. the cost of a repair is a function of the time spent by the repair person.

To write an equation for the cost of a repair based on the time spent by the repair person, you can use the formula:

Cost (C) = (Hourly Rate x Time) + House Call Fee

In this case, the hourly rate is $26 and the house call fee is $38. So the equation becomes:

C = (26 * Time) + 38

Where C represents the cost of the repair and Time represents the number of hours spent on the repair.

Let's say the repair person spent 3 hours on the repair, you can substitute it into the equation to find the cost:

C = (26 * 3) + 38
C = 78 + 38
C = 116

Therefore, the cost of the repair would be $116.
