Solve the problem.A company has three factories I, II, and III. Each factory employs both skilled and unskilled worker. The break down of the number of workers by type in the three factories is summarized by matrix A below. The hourly wage of the skilled worker is $15 and that of the unskilled worker is $10. Multiply appropriate matrices and compute the total hourly pay at each factory. A =?

Question

What will be an ideal response?

Answer 1

Let B = [ 15 10 ]. Then BA = [ 795 1040 980 ].
Therefore, the total hourly pay for factory I = $795, for II = $1,040, and for III = $980.
