Question

The plumber charges a service fee of $45 when he comes to your house. He also charges $25 per hour while he does the repairs. The total bill was $400. Which equation represents this situation? *

Answer 1

Explanation:

There is a flat fee of $45 which will be added to his $25 per hour rate.

Let h represent the hours he worked. The total of final bill is $400.

45 + 25h=400

-45 -45

25h=355

25 25

Therefore h =14.2 hours
