I Get A Little Confused With The Fifo/lifo Methods. Can You Tell Me If I Have Figured These Questions Right?

The hospital for Ordinary surgery uses pharmaceuticals for its patients. It started the year on Jan 1 with an inventory of 1000 doses of an antibiotic drug that cost $17 per dose. On Jan 2, it purchased another 300 doses for $21 each. From January 3 through June 30 it used 800 doses. On July 1. it bought 500 more doses at $23 each. From July 2 through the end of the year it used 400 doses. What is the inventory value at the end of the year, assuming FIFO? What is the value assuming LIFO?
