Please just explain the red line part. How this function should be 2p-1T >= 0, instead of p -2T >= 0 . Please provide more details about the second constraint to explain how it formed. Thank you.

The constraints for the objective function are as follows: Constraint 1: P+T2250 Constraint 2: : 2 How 2P -T20 Constraint 3: P20 PharmaPlus operates a chain of 30 pharmacies. The pharmacies are staffed by licensed pharmacists and pharmacy technicians. The company currently employs 85 full-time equivalent pharmacists (combination of full time and part time) and 175 full-time equivalent technicians. Each spring management reviews current staffing levels and makes hiring plans for the year. A recent forecast of the prescription load for the next year shows that at least 250 full-time equivalent employees (pharmacists and technicians) will be required to staff the pharmacies. The personnel department expects 10 pharmacists and 30 technicians to leave over the next year. To accommodate the expected attrition and prepare for future growth, management stated that at least 15 new pharmacists must be hired. In addition, PharmaPlus's new service quality guidelines specify no more than two technicians per licensed pharmacist. The average salary for licensed pharmacists is $40 per hour and the average salary for technicians is $10 per hour. a. Determine a minimum-cost staffing plan for PharmaPlus. How many pharmacists and technicians are needed? b. Given current staffing levels and expected attrition, how many new hires (if any) must be made to reach the level recommended in part (a)? What will be the impact on the payroll
