Community coffee company wants a new flavor of cajun coffee. how many pounds of coffee worth $7 a pound should be added to 20 pounds of coffee worth $2 a pound to get a mixture worth $5 a pound

Let us say that:

x = pounds of $7 coffee

So that:

7 x + 2 * 20 = 5 * (x + 20)

7x + 40 = 5x + 100

2x = 60

x = 30 pounds

Therefore 30 pounds should be added.

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.
