question 27

Multiple Choice

first two games of the season. Write a matrix containing the total number of points and rebounds for each of the starting
five.
$$\begin{array}{l}\begin{array} { l | c | c } \text { Game } 1 & \text { Points } & \text { Rebounds } \\\hline \text { Levy } & 20 & 3 \\\text { Cowens } & 16 & 5 \\\text { Williams } & 8 & 12 \\\text { Miller } & 6 & 11 \\\text { Jenkins } & 10 & 2\end{array}\\\\\begin{array} { l | c | c } \text { Game } 2 & \text { Points } & \text { Rebounds } \\\hline \text { Levy } & 18 & 4 \\\text { Cowens } & 14 & 3 \\\text { Williams } & 12 & 9 \\\text { Miller } & 4 & 10 \\\text { Jenkins } & 10 & 3\end{array}\end{array}$$

A) $\left[ \begin{array} { l l } 5 & 62 \end{array} \right]$
В) $\left[ \begin{array} { r r } 7 & 38 \\ 30 & 8 \\ 21 & 20 \\ 21 & 10 \\ 5 & 20 \end{array} \right]$
C) $\left[ \begin{array} { r r } 38 & 7 \\ 30 & 8 \\ 20 & 21 \\ 10 & 21 \\ 20 & 5 \end{array} \right]$
D) $[ 625 ]$ Answer: C
-A bakery sells four main items: rolls, bread, cake, and pie. The amount of each of five ingredients (in cups, except for eggs) required to make a dozen rolls, a loaf of bread, a cake, or a pie is given by matrix A.
Suppose a day's orders total 20 dozen rolls, 200 loaves of bread, 50 cakes, and 60 pies. Write the orders as a $1 \times 4$ matrix and, using matrix multiplication, find a matrix for the amount of each ingredient needed to fill the day's orders.
