can someone help me with this managerial accounting practice problem. the last answer choice is 482000 it wouldnt fit on the screen.

Carp Corporation is considering whether to replace a machine that was purchased 7 years ago for $518,000. This machine was used to make product AB until at broke down last week. They have the option to purchase either Model 264 machine costing $523,000 or a Model Y87 costing $482,000. Management has decided to buy Model Y87. It has less capacity than the Model 764 but its capacity is sufficient to continue making product ABI. Management also considered, but rejected, the alternative of simply dropping product ABl. If that were done, instead of investing 5482,000 in the new machine, the money could be invested in a project that would return a total of $497,000, in making the decision to buy Model Y87 instead of Model 264, the sunk cost was: Multiple Choice 5523000 $497.000 $518,000
