Problem 7_{Question Value: 4) ABC Electronics must buy a piece of equipment to place electronic components on the printed circuit boards it assembles. The proposed equipment has a 10-year leife with no scrap value. The supplier has given JT several purchase alternatives. The first is to purchase the equipment for $855,000 (Option A). The second is to pay for the equipment in 10 equal installments of $135,000 each, starting one year from now (Option B). The third is to pay $195,000 now and $95,000 at the end of each year for the next 10 years (Option C). Which alternative should JT choose if their MARR is 11% per year? Use an IRR comparison approach. Where JT Electronics must purchase one of the pieces of equipment, do not consider the do nothing option (Perform all calculations using 5 significant figures and round your answer to one decimal place.
