37. lowa Precision Testing (IPT) does fluid testing for local hospitals and clinics. Consider their urine testing process. each sample requires 12 seconds to test, but after 300 samples, the equipment must be re-calibrated (obviously, it can be re- calibrated sooner). No samples can be tested during the re-calibration process, and that process takes 30 minutes. Suppose 2.5 urine samples need to be tested per minute. What is the smallest batch size (in samples) that ensures that the process is not supply constrained. Instruction: Round your answer to two decimal place
