CPM Homework Help : PC Problem 12-28

How would the matrix about the Knoxville Nobles in problem 12-23 be changed if Package B were modified to include $2$ T-shirts?

Hint:

In problem 12-23, Package B included $6$ tickets, $1$ T-shirt, $$15$ in snack credits, and no poster. Hence the 2nd row of the matrix was $[ 6\:\: 1\:\: 15\:\: 0 ]$ .
