Please give step by step on how to do this and thanks.

Check your worksheet by changing the beginning work in process inventory to 300 units, the units started into production during the period to 18,200 units, and the units in ending work in process inventory to 500 units, keeping all of the other data the same as in the original example. If your worksheet is operating properly, the cost per equivalent unit for materials should now be $20.78 and the cost per equivalent unit for conversion should be $19.67. If you do not get these answers, find the errors in your worksheet and correct them.
