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.

Step-by-step explanation:

The given information can be tabulated as follows:

                          Graphics G     Printing P            Total

X                                      3                 2                    5

Y                                      1                  1                      2

Available                       21                19

We have the constraints as

Thus we have solutions as
