McPherson Furniture Company started construction of a combination office and warehouse building for its own use at an estimated cost of $5,000,000 on January 1, 2012. McPherson expected to complete the building by December 31, 2012. McPherson has the following debt obligations outstanding during the construction period.

Instructions
(Carry all computations to two decimal places.)
  (a) Assume that McPherson completed the office and warehouse building on December 31, 2012, as planned at a total cost of $5,200,000, and the weighted average of accumulated expenditures was $3,800,000. Compute the avoidable interest on this project.
  (b) Compute the depreciation expense for the year ended December 31, 2013. McPherson elected to depreciate the building on a straight-line basis and determined that the asset has a useful life of 30 years and a salvage value of $300,000.
