The numbers of three types of bank accounts on January 1 at the Central Bank and its branches are represented by matrix A. Fixed- Checking accounts deposit Savings accounts accounts Main office A = Westside branch 1030 Eastside branch L1170 2820 1490 1120 520 460 560 460 The number and types of accounts opened during the first quarter are represented by matrix B, and the number and types of accounts closed during the same period are represented by matrix C Thus, 260 120 110 [ 120 80 80 B = 140 60 50 and C= 70 30 40 120 70 50 60 20 40 (a) Find matrix D, which represents the number of each type of account at the end of the first quarter at each location. D = (b) Because a new manufacturing plant is opening in the immediate area, it is anticipated that there will be a 10% increase in the number of accounts at each location during the second quarter. Write a matrix E = 1.1D to reflect this anticipated increase. E =
