Please help with the second question only posting the first one because it is needed for the second question. Please show all work.

A medical imaging facility is considering the purchase of a positron emission tomography(PET) or a single, photon emission computed tomography (SPECT) as mutually exclusive options. Additionally, the facility is considering the purchase of a computerized tomography(CT) contingent on the purchase of PET or SPECT. Alternatively, the facility can purchase combination equipment PET/CT or SPECT/CT as additional mutually exclusive options. Thus, the list of mutually exclusive purchase options is O (PET). [SPECT). PET, SPECT). (PET. CIT. ESPECT. CEL (PET, SPECT, CT. PET/CT). [SPECT/CT) O PET ISPECT. ICTL (PET, CT), (SPECT, CT), (PET/CTI. [SPECT/CT O PETI, ISPECT). ICT. PET, SPECI). PET, CT. ISPECT. CIT. (PET. SPECT, CH. (PET/CT. SPECTACT O PETI. [SPECT), IPET, CT). [SPECT, CT). (PET/CT). [SPECT/CT| Suppose that the options in Question 10 are narrowed down to (SPECT, CT) and (PET/CT). Particularly, (SPECT, CT) costs $110,000, is expected to last 6 years with a salvage value $10,000, and has operating cost of $14 per test. (PET/CT) costs $160,000, should last 6 years with a salvage value $14,000, and has operating cost of $6 per test. The interest rate is assumed to be 14%. If the facility plans to conduct on average 2,000 tests per year, which option should be selected O (SPECT, CT O ISPECT, CT and [PET/CT) O PET/CT) O Neither
