Question 5 1 pts You consider purchasing a computer system for $12,000. Annual upgrades will cost $500. Your expected salvage value is $1000 at the end of 5 years. The system is faster and will save you $4000 per year over your current system. If the interest rate = 10%: EUAC = 12000 + 500(P/A, 10%,5) - 1000(P/F,10%,5) EUAC = 12000(A/P,10%,5) + 500-1000(A/F,10%,5) EUAC = 12000(A/P,10%,5) - 500-1000(A/F,10%,5) EUAC = 12000(A/P, 10%,5) - 500+ 1000(A/F, 10%,5)
