The balance sheet value of a firm's inventory is $65,000. Suppose that the firm purchases supplies at a cost of $3,500 and adds them to inventory. A day later, the market value of the recently purchased supplies changes to $5,000.

Assuming no other changes to inventory, and using the historical cost method, what is the final balance sheet value of inventory?

Note: Students with prior accounting experience should not apply the monthly "lower of cost or market" adjustment. This is a day-to-day fluctuation.
