To find out how many hours the electrician worked, we can set up an equation based on the given information.
We know the total charge is made up of a $50 traveling fee plus $90 per hour for the time worked. We can express the total charge (C) as:
\[
C = 90h + 50
\]
where \( h \) is the number of hours worked.
We know that the total charge is $410, so we can set up the equation:
\[
410 = 90h + 50
\]
Now, we can solve for \( h \):
1. Subtract $50 from both sides:
\[
410 - 50 = 90h
\]
\[
360 = 90h
\]
2. Now, divide both sides by 90:
\[
h = \frac{360}{90} = 4
\]
Thus, the electrician worked **4 hours**.
