Mark is creating a tarp to cover his new vegetable garden outside. he needs enough nylon to cover the garden which is 10 feet by 8 feet and then he will attach rope along the edges of the nylon to stake it down with. he goes to the store and the nylon costs $5.25 a square yard and the rope is $1.25 a foot. how much will it cost him to make the cover?

$91.67.

Step-by-step explanation:  

We have been given that Mark is creating a tarp to cover his new vegetable garden outside. He needs enough nylon to cover the garden which is 10 feet by 8 feet and then he will attach rope along the edges of the nylon to stake it down with.

A. Let us find area covered by nylon by multiplying 10 by 8.

Now let us convert area of needed nylon from square feet into square yard by multiplying 80 by 0.111111.

Now let us multiply 8.88889 by 5.25 to find the cost of nylon cover of the garden.

Therefore, the cost of nylon cover will be $46.67.

B. Now let us find length of rope by finding the perimeter of the garden.

Now let us find the cost of 36 feet long rope by multiplying 36 by 1.25.

Therefore, the cost of rope will be $45.

To find the total cost to make the cover we will add cost of nylon cover and cost of rope.

Therefore, it will cost $91.67 for Mark to make the cover for vegetable garden.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

you are only given the cost not the amount of pounds.
