Answer:
The electrician charges $40 to come to your house and $55 per hour, so the answer is 3 hours
Step-by-step explanation:
We can subtract the $40 out of the $190 and we will have $150 left.
If the electrician charges $55 dollars per hour so we can divide $150/$55 which will be 2.72727272 and then we can round it off to 3 hours.
Hope this helps.
