Check Mark

Answer to Problem 34P

The difference in EUAC’s is $5,325

Explanation of Solution

Upgrade option

Cost of upgrade = $12,000, i = 15%, n = 9 years

  EUAC of upgrade option=Cost×( A/P,i%,n)                                         =12,000×( A/P,15%,9)                                         =12000×0.2095                                         =$2,515

Labor intensive option

  Direct labor cost = $3,500Indirect plant expenses = 60%×3500                                     = $2,100Office overhead = 40%×(3500+2100)                          = $2,240

   EUAC of labor intensive option=3500+2100+2240 =$7840

  Difference in EUAC’s of both options=EUAC of labor optionEUAC of upgrade option                                                             = 78402515                                                             = $5,325
