A plumber charges a base fee of $55 for a service call plus $35 per hour for each hour worked during the service call.
Use your equation to calculate how much money it will cost if the plumber works 4 hours
To calculate how much it will cost if the plumber works for 4 hours, we need to add the base fee to the cost for the number of hours worked.
Let's break it down step by step:
Step 1: Determine the cost for the number of hours worked
The plumber charges $35 per hour for each hour worked during the service call. So, for 4 hours, the cost will be:
$35 x 4 hours = $140
Step 2: Add the base fee to the cost for the hours worked
The base fee is $55. Adding this to the cost for the hours worked gives us:
$55 + $140 = $195
Therefore, if the plumber works for 4 hours, it will cost $195.
cost = 55 + 35 h
