My rule is: take a number, add 15, and then subtract 9. Write down the rule.

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.
