Manuel builds and sells wooden crates. he made this table to show how much his crates cost in dollars. number of crates: 2 4 6 8 cost ($): $25 $45 $65 $85 identify the location where manuel's number of crates equals zero in the format (x, y).

So there are two ways I see this problem.

First as trick question kinda, due to the fact that it is a word problem and the way it is setup would make me think the answer is 0,0. You don't pay anything for 0 crates.

The other way is by graphing it.
We can take the points and just plug it into

First lets solve for for

putting in point one and two on the table here gives us 10

The problem here is we don't know the Y intercept which makes finding the equation a tad harder, we are going to have to find to find that as well. It is pretty simple though we can just plug in a random point to make it a solvable problem . We can then work this out to b = 5

From there we have found the equation with it being . Putting that into our graph gives us a Y intercept of 5 and a X intercept of -0.5.

Sorry if I went a bit far there, hope you can figure the problem with one of those.

On monday,mrs.wise bought 3 lbs of apples at $4per lb= 4*3=$12on tuesday ,20%off and she buy 5 lbs of apples = $4-20%=3.20*5lb=$16example: other wise when she buy 5lbs on monday she have to spend 4*5=20
