The internal audit department discovered the following items:

Goods valued at $32,000 held on consignment from Dix Company were included in the physical count but not recorded as a purchase.

Purchases from Xavier Corporation were incorrectly recorded at $41,000 instead of the correct amount of $14,000. The correct amount was included in the ending inventory.

Goods that cost $25,000 were shipped from a vendor on December 28, 2013, terms f.o.b. destination. The merchandise arrived on January 3, 2014. The purchase and related accounts payable were recorded in 2013.

One inventory item was incorrectly included in ending inventory as 100 units, instead of the correct amount of 1,000 units. This item cost $40 per unit.

The 2012 balance sheet reported inventory of $352,000. The internal auditors discovered that a mathematical error caused this inventory to be understated by $62,000. This amount is considered to be material.

Goods shipped to a customer f.o.b. destination on December 25, 2013, were received by the customer on January 4, 2014. The sales price was $40,000 and the merchandise cost $22,000. The sale and corresponding accounts receivable were recorded in 2013.

Goods shipped from a vendor f.o.b. shipping point on December 27, 2013, were received on January 3, 2014. The merchandise cost $18,000. The purchase was not recorded until 2014.

Determine the correct amounts for 2013 ending inventory, purchases, accounts payable, sales revenue, and accounts receivable.
