I am looking to decide between staying in my current home or moving to a new home. The new home would cost $250,000 and needs no repairs. I originally paid $115,000 for my home and needs $80,000 in work because the roof and shingles need to be replaced. The new house is much closer to work, which would result in a savings of $10,000 per year in gas and other vehicle costs. Which cost would be irrelevant in my decision making process? Select one: a. gas and vehicle costs b. the cost of repairs on the original home c. the cost of the new house d. the original cost of the house
