____ 3. (CPA adapted) A manufacturer expects to produce 200,000 widgets during the fiscal year ending June 30, 2011, to supply the demand that is uniform throughout the year.

After a batch of widgets is produced and placed in inventory, it is sold at a uniform rate and inventory reaches zero when the next batch of widgets is completed. The quantity of widgets (rounded to the nearest one hundred widgets) that would be produced in each run in fiscal year 2011 to minimize total annual relevant setup and carrying costs is:

a. 12,000.

b. 12,500.

c. 16,000.

d. 17,000.

e. 19,000.
