Mrs. Schneider purchases twenty donuts and thirty cookies at a donut shop and is charged $33. Briana purchases five donuts
and two cookies at the same shop for $4.95. All the donuts have the same price. Find the cost of one donut and find the cost of one cookie

The donuts cost $0.75 and the cookies cost $0.6

Step-by-step explanation:

You need to create a system of equations:

20d + 30c = 33

5d + 2c = 4.95

Now, let's isolate the cookies on the second equation:

2c = 4.95 - 5d

Multiply it per 15 to get the value of 30 cookies:

30c = 74.25 - 75d

Substitute in the first equation:

20d + 74.25 - 75d = 33

-55d = -41.25

d = -41.25/-55

d = 0.75

Now substitute the value of d in the second equation to find the value of c:

5•0.75 + 2c = 4.95

3.75 + 2c = 4.95

2c = 4.95 - 3.75

2c = 1.2

c = 1.2/2

c = 0.6

step-by-step explanation:

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.
