A square garden has a 20 ft fence surrounding it. How much will it cost to mulch the garden if one bag covers 2.5 square feet and costs $3.99 per bag?

$39.90

Step-by-step explanation:

Ok square, all sides equal.

20ft fence would be perimeter.

Covers is area.

20/4=5

5 is the length of each side.

A=5*5

A=25

one bag=2.5

25=2.5x

x=10

it takes 10 bags of mulch.

10*3.99

$39.90 to cover it all

okay wait before i answer, is this for your points on a graph?

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.
