Problem 2 You work for a company that does blood testing and needs to invest in another centrifuge. You are looking at two different models. The first is the Unico PowerSpin LX which can hold 5 test tubes of blood when operating (per run). The second model is the Benchmark Scientific which can hold 6 test tubes when operating (per run). You charge 7 per test tube, so the Unico PowerSpin LX earns you 35 per run and the Benchmark Scientific earns you 42 per run. The Unico PowerSpin LX costs $676 to purchase and each run costs 10. The Benchmark Scientific costs $859 to purchase and costs 15 per run. a) How many runs will be needed for both machines to generate the same level of profit? | b) If the expected number of runs is 10,000, which machine should you buy
