An electrician charges $50 to come to your house. He also charges $25 for each hour he spends at your house. The electrician charges you a total of $125. How many hours did he spend at your house? Please show the equation!
50 + 25x = 125
An electrician charges $85 for a house call plus $50 per hour. How many hours did the electrician work if he changed $310?
To find the number of hours the electrician spent at your house, let's assume the unknown variable, "x," represents the number of hours.
The electrician charges $50 to come to your house, and an additional $25 for each hour spent. So, the equation to represent the total cost is:
Total Cost = Cost for Electrician's Visit + (Cost per Hour x Number of Hours)
Mathematically, this can be written as:
$125 = $50 + ($25 x x)
To solve for "x," we need to isolate it on one side of the equation. Let's rearrange the equation to do that:
$125 - $50 = $25x
Simplifying the equation:
$75 = $25x
Now, divide both sides of the equation by $25:
$75 / $25 = x
This results in:
3 = x
Therefore, the electrician spent 3 hours at your house.
