Suppose a Company Supplies Four of Its Products A, B

Suppose a company supplies four of its products A, B, C, and D, to five different regions. The management wants to know the total number of all products supplied to each region as well as the total number of units of each product supplied. The data collected over a period of month are given below. $$\begin{array} { | c | c | c | } \hline \text { Region } & \text { Model } & \begin{array} { c } \text { Number of } \\\text { units }\end{array} \\\hline \text { Region 1 } & \text { A } & 1784 \\\hline \text { Region 2 } & \text { A } & 2170 \\\hline \text { Region 3 } & \text { A } & 415 \\\hline \text { Region 4 } & \text { A } & 2040 \\\hline \text { Region 5 } & \text { A } & 2991 \\\hline \text { Region 1 } & \text { B } & 947 \\\hline \text { Region 2 } & \text { B } & 2111 \\\hline \text { Region 3 } & \text { B } & 1234 \\\hline \text { Region 4 } & \text { B } & 2061 \\\hline \text { Region 5 } & \text { B } & 607 \\\hline \text { Region 1 } & \text { C } & 2907 \\\hline \text { Region 2 } & \text { C } & 4790 \\\hline \text { Region 3 } & \text { C } & 2191 \\\hline \text { Region 4 } & \text { C } & 1942 \\\hline \text { Region 5 } & \text { C } & 220 \\\hline \text { Region 1 } & \text { D } & 2557 \\\hline \text { Region 2 } & \text { D } & 2980 \\\hline \text { Region 3 } & \text { D } & 1518 \\\hline \text { Region 4 } & \text { D } & 2957 \\\hline \text { Region 5 } & \text { D } & 4462 \\\hline\end{array}$$ ​
