    Step-by-step explanation:

    First, write an equation. 55x+40=190.

    X represents the hours the electrician works. The 55 represents the $55 that she charges for each hour she works. The + 40 for the $40 that was the price just to come to your house. The 190 is the total cost. Now, solve that equation.

    55x+40=190

    55x=150

    x=2.72727272 ...

    So the answer is 2.727 hours. It can be rounded as needed or turned into a decimal, 2 8/11.
