1) A particular linear programing problem is formulated as follows:
Min. Z= 2500x+3500y
Subject to:
5x + 6y > 250
4x + 3y > 150
x + 2y > 70
x, y > 0
Draw these constraints on graph paper (or excel) and determine the optimum solution.
a. Set up the problem in mathematical form
b. Solve the problem by the graphical method

2) A manufacturer produces two products, P and Q, which when sold earn contributions of \$600 and \$400 per unit respectively. The manufacture of each product requires time on a lathe and a polishing machine. Each unit of P requires 2 hours on the lathe and 1 hour on the polishing machine, while Q requires 1 hour on each machine. Each day, 10 hours are available on the lathe and 7 hours on the polishing machine. Determine the number of units of P and Q that should be produced per day to maximize contribution.
a. Set up the problem in mathematical form
b. Solve the problem, using either graphical or computer method, show your work.
