The answer is D because using division you would find how many cups you need to sell.
You can resolve all of them.
so the first one would be 3q+2p
that second 2p+3q
the third 2p+2q+q which equals 2p+3q
they all end up as the same thing so both are equivalent
The other end point is 0,4
I believe that the answer is 120 marbles.<span />
