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

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

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
