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.

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
