heeeeelp

myininaya (myininaya):

Let's look at team A for a sec.

myininaya (myininaya):

We have 3 TDs. And each TD is worth 6 points. So how many points in all does Team A have from TDs?

OpenStudy (anonymous):

18?

myininaya (myininaya):

right and Team A has 2 FGs and each FG is worth 3 points? So FG points in all?

OpenStudy (anonymous):

6

myininaya (myininaya):

right no so far we have 18+6+something else points for Team A we have 1 S and 0 PAT so S is worth 2 points each so you have 2 points in all for S and no points for Pat? 18+6+2 is what team A has

OpenStudy (anonymous):

so 26 for team A

OpenStudy (anonymous):

There's only one choice like that, so that's my answer. C

OpenStudy (anonymous):

Thank you so much :)

myininaya (myininaya):

you could have gotten this by setting a 2 by 4 matrix with a 4 by 1 matrix where the 2 by 4 matrix gives row 1 as team A's numbers and row 2 gives team B's numbers The second matrix is just how much those numbers count
