DECISION SCIENCE Assume more restrictions. The books pass through two departments: Graphics and Printing, 1. before they can be sold, X requires 3 hours in Graphics and 2 hours in printing. Y requires 1 hour in graphics and 1 hour in printing. There are 21 hours available in graphics and 19 hours in printing respectively. Solve for x and y.

Answer:Step-by-step explanation:The given information can be tabulated as follows:                           Graphics G     Printing P            TotalX                                      3                 2                    5Y                                      1                  1                      2Available                       21                19We have the constraints as[tex]3x+y\leq 21\\2x+y\leq 19\\x\leq 2\\y\leq 15[/tex]Thus we have solutions as[tex]0\leq x\leq 2\\0\leq y\leq 15[/tex]
