    Answer: the electrician's hourly labor rate is $25

    Step-by-step explanation:

    Let x represent the electrician's hourly labor rate.

    The electrician charges a $40 dollar fee to make a house call plus an hourly rate for labor. This means that the total bill for a job that takes y hours would be

    xy + 40

    If the total bill for a job that takes 2 hours comes to $99, it means that

    2x + 40 = 90

    2x = 90 - 40

    2x = 50

    x = 50/2

    x = 25
