Krista needs her kitchen sink repaired. She pays a plumber a flat fee for an initial consultation, and then she pays him an hourly rate for the time he works on the repair. The equation y = 25x + 40 represents this situation, where x is the number of hours and y is the total cost. What does the number 40 in the equation represent?

Answer:

The "40" represents the flat fee (for an initial consultation).

Step-by-step explanation:

The equation is in slope-intercept form, [tex]y=mx+b[/tex], where the mx is the rate of change and the b is like the flat fee, or the base amount.

I hope that helps! :)
