to assemble. Model B requires 3 hours to stain and finish and 1 hour to assemble. The total amount of
time available for staining and finishing is 24 hours and for assembling is 12 hours. Let x represent the
number of Model A desk produced, and let y represent the number of Model B desks produced.
a) Write two inequalities that express the fact that the number of desks to be produced cannot be
negative.
b) Write an inequality in terms of the number of Model A and Model B desks that can be produced if the
total time for staining and finishing is at most 24 hours.
