Answer:
some information was missing, the present value of the equipment which is $65,000
the journal entries to record the lease agreement is:
January 2, 2015, five year lease for machinery
Dr Machinery 65,000
Cr Lease liability 65,000
then you must record the lease payment, since it is done immediately, there is no interest expense recorded:
January 2, 2015, first annual lease payment
Dr Lease liability 15,000
Cr Cash 15,000
Only the first lease payment will not include an interest expense since it was done the same day as the machinery was leased.
