12-29.

On Team Support Day, the Nobles announce they will give away an extra team poster with every package sold that day. Homework Help ✎

How does this modify the matrix?

Suppose that during the day the team sold 40 Package A’s, 20 Package B’s, 50 Package C’s, and 5 Package D’s. How many tickets did they sell? How many posters?

In problem 12-24, Packages A and B had no posters, Package C had one poster, and Package D had ten posters. This was represented by 0, 0, 1, 10 in the fourth column.

What part of the resulting matrix represents the total tickets sold? What about the total posters sold?
