Use the information below to answer the following questions.
A chemical company produces two products (A & B) that are sold as raw materials to companies manufacturing bath soaps and laundry detergents. Management has specified that the combined production of products A and B must total at least 350 gallons. A major customer order for 125 gallons of product A must be satisfied. Product A requires 2 hours of processing time and Product B requires 1 hour of processing time. There are 600 hours of processing time available to complete the necessary work. The company desires to satisfy the requirements stated at the minimum total production cost. Production costs are $2 per gallon for product A and $3 per gallon for product B. Assume that the variable “AP” represents the number of units of A that are produced and “BP” represents the number of units of B that are produced.
Which of the following are valid constraints for the problem.
AP + BP
AP + BP = 125
2AP + BP
All of the above
None of the above
