Solve the problem.A computer manufacturer has three outlet stores that sell its four computer systems. The following table shows the numbers of systems sold by the three stores in July. 
The prices of the systems are: $1200 for System 1, $1500 for System 2, $1600 for System 3, and $2100 for System 4. Write the information from the table as a 4 x 3 matrix B. Write a row matrix A for which the entries represent the prices for the systems. If C = AB, find c11 . What does this entry of C represent?
A. c11 = 153,000. c11 represents the sales of System 2 at all stores in July. B. c11 = 173,000. c11 represents the total sales at Store 3 in July. C. c11 = 163,000. c11 represents the total sales at Store 1 in July. D. c11 = 185,000. c11 represents the total sales at Store 1 in July.
