An electrician charges a $40 dollar fee to make a house call plus an hourly rate for labor. If the total bill for a job that takes 2 hours comes to $99, what is the electrician's hourly labor rate

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
