The monthly sales (in thousands) of burgers $(\mathrm{B} 1)$ and bites $(\mathrm{B} 2)$ in three fast-food restaurants $(R 1, R 2, R 3)$ are as follows: \begin{tabular}{l|ccc} & R1 & R2 & R3 \\ \hline B1 & 35 & 27 & 13 \\ B2 & 42 & 39 & 24 \end{tabular} \begin{tabular}{l|ccc} & January \\ & R1 & R2 & R3 \\ \hline B1 & 31 & 17 & 3 \\ B2 & 25 & 29 & 16 \end{tabular} (a) Write down two $2 \times 3$ matrices $\mathbf{J}$ and $\mathrm{F}$ representing sales in January and February respectively. (b) By finding $\boldsymbol{J}+\mathrm{F}$, write down the matrix for the total sales over the two months. (c) By finding $J-F$, write down the matrix for the difference in sales for the two months.

A company stores and sells air conditioning units, electric heaters and humidifiers. Row matrix A represents the number of each unit sold last year, and matrix $B$ represents the profit margin for each unit. Find $A B$ and describe what the product represents. $A=(235 \quad 562 \quad 117), B=\left(\begin{array}{c}\epsilon 120 \\ 695 \\ 656\end{array}\right)$

00:02 During the month of january, abc appliances sold 45 microwaves, 12 refrigerators, and 30 stoves, while xyz appliances sold 49 microwaves, 12 refrigerators, and 21 stoves.
00:15 For part a, we want to write a 2x3 matrix summarizing the sales for the month of january.
00:21 So let's keep them in order.
00:23 45 microwaves, 12 refrigerators, 30 stoves.
00:31 And then xyz sold 49 microwaves, 12 refrigerators, and 21 stoves.
00:50 For part b, we're added 2x3 matrix summarizing the month of february.
00:56 In february, let's go in the same order where the first row is abc appliances, microwaves, refrigerator, stoves...
