Two years ago the Krusty Krab Restaurant purchased a grill for $50,000. The owner,
Eugene Krabs, has learned that a new grill is available that will cook Krabby Patties
twice as fast as the existing grill. This new grill can be purchased for $80,000 and
would be depreciated straight line over 8 years, after which it would have no salvage
value. Eugene Krab expects that the new grill will produce EBITDA of $50,000 per
year for the next eight years while the existing grill produces EBITDA of only $35,000
per year. The current grill is being depreciated straight line over its useful life of 10
years after which it will have no salvage value. All other operating expenses are
identical for both grills. The existing grill can be sold to another restaurant now for
$30,000. The Krusty Krab’s tax rate is 35%.If the Krusty Krab’s opportunity cost of
capital is 12%, what decision should the Krusty Krab take regarding the new grill?
A) Do not install the new grill since NPV is approximately = – $10,630
B) Install the new grill since NPV is approximately = + $10,630
C) Install the new grill since IRR is approximately = 15%
D) Don’t install the new grill since IRR is less than 12%
