Let x = long sleeved shirts
Let y = short sleeved shirts
a) 4x + 3y <= 120
b) 3x + 1y <= 60
d) (0, 40) (20,0), but answers can vary
e) The best solution on the graph is where the two inequalities intersect, making it a critical point which is (12, 24).
Profit made:
12 long sleeved shirts = $13.20
24 short sleeved shirts = $14.40
