7-172.

Each #1 bouquet has $5$ lilies, $4$ roses, and $3$ daisies. Each #2 bouquet has $4$ lilies, $3$ roses, and $3$ daisies. Each #3 bouquet has $4$ lilies, $6$ roses, and $6$ daisies.

1. Arrange this information in a new matrix with bouquet styles as rows. What will be the columns of this new matrix? Label the rows and columns of the matrix and call it matrix B.

If the rows are labeled with bouquet styles, the columns must be labeled with flower types.

{\begin{aligned}[c] \text{l r d} \; \; \,\\ B= \begin{array}{l} \text {#1}\\ \text {#2}\\ \text {#3} \end{array} \quad \left[\begin{array}{&c&c&c} 5 & 4 & 3 \\ 4 & 3 & 3\\ 4 & 6 & 6 \end{array}\right] \end{aligned}}

2. Using the row-by-column labels, what will matrix B represent?
