Abarber working 8 hours a day must make $10 an hour to cover his expenses. suppose he
makes $12 per haircut. how many haircuts must he do each day (8 hours) to ensure he will
cover his expenses?

7 Haircuts each day.

Step-by-step explanation:

Let us first find out the amount a barber required to cover his expenses:

8 x 10 = $80

$80 is the total amount barber required to cover his expenses.

Now, if a barber makes $12 per haircut, Let us find out the total number of haircuts he has to do in order to meet his expenses. So;

80 / 12 = 6.67 = 7

So for a barber to cover his expenses, he has to do 7 haircuts each day.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
