In this activity you will perform matrix operations to solve problems. Part A Table 1 contains data on unit sales of notebook computers by three sales teams of Computer Gear Corporation in three cities for the first quarter of last year. Table 2 contains the sales data for the second quarter. Table 1: First Quarter Sales City Team A Team B Team C New York City 112 89 101 Chicago 78 82 43 Phoenix 91 96 103 Table 2: Second Quarter Sales City Team A Team B Team C New York City 81 63 92 Chicago 68 72 56 Phoenix 71 76 89 Use matrices to compute the midyear sales report. What does the middle entry, C22, of the resultant matrix represent?
