On a large construction project, the price of sheet lumber per square foot is $.30 and spraying the lumber with an anti-termite agent is $.40 per square yard. how much must the construction firm pay for a sprayed sheet of lumber that is 90 square yards?

$117

Step-by-step explanation: notice it tries to trick you a little because lumber is $.30 for every FOOT so knowing there is 3 feet in a yard your first step is to (.30*3=.90) then you can add $.40 and get 1.3 Finally multiply to get your answer (1.3*90=117)

over the argument its not good to fight.

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.
