Bramble Corp. began the year with 10 units of marine floats at a cost of $12 each. During the year, it made the following purchases: May 5, 32 unit at $16; July 16, 19 units at $20; and December 7, 24 units at $23. Assume there are 35 units on hand at the end of the period. Bramble uses the periodic approach.
