Explanation / Answer

ANSWER: I AM SOLVING QUESTION NO 23 AS FOR OTHER QUESTION IS INCOMPLETE AS IT CANNOT BE SEEN FULLY.

23) maintenance cost = $270

i = 5% per year

increase in cost = $90

n = 6 years

maintenance cost in 1st year = $270

maintenace cost in 2nd year = maintenance cost in 1st year + increase in cost = $270 + $90 = $360

maintenace cost in 3rd year = maintenance cost in 1st year + increase in cost = $360 + $90 = $450

maintenace cost in 4th year = maintenance cost in 1st year + increase in cost = $450 + $90 = $540

maintenace cost in 5th year = maintenance cost in 1st year + increase in cost = $540 + $90 = $630

maintenace cost in 6th year = maintenance cost in 1st year + increase in cost = $630 + $90 = $720

pw = maintenance cost in 1st year(p/f,i,n) + maintenance cost in 2nd year(p/f,i,n) + maintenance cost in 3rd year(p/f,i,n) + maintenance cost in 4th year(p/f,i,n) + maintenance cost in 5th year(p/f,i,n) + maintenance cost in 6th year(p/f,i,n)

pw = 270(p/f,5%,1) + 360(p/f,5%,2) + 450(p/f,5%,3) + 540(p/f,5%,4) + 630(p/f,5%,5) + 720(p/f,5%,6)

pw = 270 * 0.9524 + 360 * 0.907 + 450 * 0.8638 + 540 * 0.8227 + 630 * 0.7835 + 720 * 0.7462

pw = 257.15 + 326.52 + 388.71 + 444.258 + 493.605 + 537.264

pw = $2,447.51

euac = pw(a/p,i,n)

i = 5% and n = 6 years

euac = 2,447.51(a/p,5%,6)

euac = 2,447.51 * 0.197

euac = $482.158

hence option c is the right answer.
