Question: Solve the systems of equations .It is necessary to set up the appropriate equations. All numbers are accurate to at least three significant digits.
A medical supply company has 1150 worker-hours for production, maintenance, and inspection. Using this and other factors, the number of hours used for each operation,P , M, and I, respectively, is found by solving the following system of equations:
P + M + 1 = 1150
P = 4I - 100
P = 6M + 50
