Please help me on this journal entry:

Interest of $2,500 had accrued on revenue anticipation notes as of year-end (see transaction 7-b-2)

Transaction 7b2:

1. [Para. 7-b-2] Equipment costing $300,000 was purchased on July 1, 2014. Cash in the amount of $200,000 was paid at the time of purchase; the vendor accepted revenue anticipation notes in the amount of $100,000 to finance the remainder of the equipment. Of this amount, $50,000 of the notes will be payable on July 1, 2015; the other $50,000 will be payable on July 1, 2016. All notes bear interest at the rate of 5 percent per year. (Record only the purchase and the related payment of cash and issuance of notes at this time; interest will be recorded in a later transaction.)
