Temblador Corporation Purchased a Machine 7 Years Ago for $319,000

Temblador Corporation purchased a machine 7 years ago for $319,000 when it launched product E26T. Unfortunately, this machine has broken down and cannot be repaired. The machine could be replaced by a new model 330 machine costing $323,000 or by a new model 230 machine costing $285,000. Management has decided to buy the model 230 machine. It has less capacity than the model 330 machine, but its capacity is sufficient to continue making product E26T. Management also considered, but rejected, the alternative of dropping product E26T and not replacing the old machine. If that were done, the $285,000 invested in the new machine could instead have been invested in a project that would have returned a total of $386,000.
-In making the decision to buy the model 230 machine rather than the model 330 machine,the differential cost was:

A) $34,000
B) $38,000
C) $4,000
D) $67,000
