Three alternative insulations are being considered for installation on a machine part. After the initial installation, if the insulation fails in any future year, it is replaced by an identical one at a cost lower than the initial cost. The costs and probabilities of failure in any year are given in the table below.

Question
Three alternative insulations are being considered for installation on a machine part. After the initial installation, if the insulation fails in any future year, it is replaced by
an identical one at a cost lower than the initial cost. The costs and probabilities of failure in any year are given in the table below.
Insulation
thickness
2 inches
3 inches
6 inches
Initial
installation cost
$900
$1,200
$1,800
Probability of failure
in any given year
26.7%
14.4%
6.32%
Replacement cost anytime
insulation fails in future
$600
$800
$1,200
If the analysis period is infinte (i.e, N = infinity), calculate the expected EUAC of the 2-inch insulation. The MARR is 11% per year.
OA. $414
O B. $259
O C. $104
O D. $155
