I have been working on this assignment for two days now, and I just can’t seem to get the dang thing to balance. Any help is appreciated. I have to prepare May journal entries for the following, then do a trial balance. Investment of $1250. Purchase of equipment for $2000 by paying $800 cash and signing a note with 10% rate annually and August 31 maturity date. (this occurred on May 1) Paid $250 for supplies Paid $150 for rental equipment to be used during May Arranged for the rental of equipment during May for $200; Paid $100 cash with remaining $100 due June 1 Received$1500 for lessons provided during May Received $400 in fees for the use of the equipment during May Paid $600 in wages during May Provided two lessons @ $55 each that was paid in April Paid $120 for misc expenses Collected $35 on account Received $800 for salary Paid $90 on account Withdrew $270 Leftover supplies equal $150 Depreciation on equipment totaled $50 Determine accrued interest. As of April 30, Cash has 2175 balance; A/R has 50; Supplies has 120; A/P has 35; Unearned Rev has 200; Capital has 500; Drawing has 300; Fees earned has 2000; Rent expense has 60 and Misc expense has 30. I don’t know what I am doing wrong, but I keep getting different answers each time. Here are the journal entries that I have come up with.
