A factory manufactures 2 products each requiring the use of 3 machines. The first machine can be used at most 70 hours; the second machine at most 40 hours; and the third machine at most 90 hours. The first product requires 2 hours on machine 1, 1 hour on machine 2 and 1 hour on machine 3. The second product requires 1 hour each on machines 1 and 2, and 3 hours on machine 3. If the profit is \$40 per unit for the first product and \$60 per unit for the second product, find the maximum profit. A factory manufactures 2 products each requiring the use of 3 machines.
