    Answer: the electrician's hourly labor rate is $29.5

    Step-by-step explanation:

    Let x represent the electrician's hourly labor rate.

    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 expressed as

    xy + 40

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

    2x + 40 = 99

    2x = 99 - 40

    2x = 59

    x = 59/2 = 29.5
