I need assistance answering the following two word problem math questions. Please note any sources used needed to be cited in APA format. For all math done, the work needs to be showed:
3.Compared with a drip system, a new type of infusion pump reduces the cost of administering chemotherapy from $25 per dose to $20 per dose. The complication rate of each system is 2 percent. Which should you choose? What sort of analysis should you do?
4.You are comparing replacing the current lab, which has a cost function of C = 200,000 + 25 × Q, with an automated lab that has a cost function of C = 300,000 + 20 × Q. Doing so would reduce the error rate from 1.5 percent to 1 percent. Your volume is expected to be 18,000 tests per year. Should you choose the automated lab? Briefly explain your logic.
Please let me know if you have any questions!
