None of the above.
Your answer is CORRECT.
Solve the following system of equations by using the inverse of the coefficient matrix.
Your answer is INCORRECT.
A certain academic department at a local university will conduct a research project. The department will need
to hire graduate research assistants and professional researchers. Each graduate research assistant will need to
work 26 hours per week on fieldwork and 14 hours per week at the university's research center. Each
professional researcher will need to work 11 hours per week on fieldwork and 29 hours per week at the
university's research center. The minimum number of hours needed per week for fieldwork is 154 and the
minimum number of hours needed per week at the research center is 131. Each research assistant will be paid
$257 per week and each professional researcher will be paid $402 per week. Let
denote the number of
graduate research assistants hired and let
denote the number of professional researcher hired. The
department wants to minimize cost. Set up the linear programming problem for this situation.
