Solve the linear programming model formulated in Problem 46 for Hoke’s Spokes by using the computer.

a. Should John Hoke try to increase his budget for purchasing bikes, increase space to stock bikes, or increase labor hours to assemble bikes? Why?

b. If John hired an additional worker for 30 hours at $10 per hour, how much additional profit would he make, if any?

c. If John purchased a cheaper cross-country bike for $1,200 and sold it for $1,900, would this affect the original solution?
