2 kinds of baseballs hard balls, soft balls.
Hard balls need 1 min. stitching and 3 min. covering.
soft balls need 2 min. stitching and 2 min. covering.
hard balls $2: soft balls $3
stitching machine is available for 100 mins.
the covering machine is available for 3 hours.
make a table, get constraints and graph.
------------------
stitching inequality: 1H+2S<=100
covering inequality: 2H+2S<=180
Profit=2H+3S
H>=0
S>=0
-------------
Solve the inequalityies for H, as follows:
H<=-2S+100
H<=-H+90
--------------
Graph the inequalities in the 1st quadrant as follows:
