During May, the number of equivalent units of materials applied to units produced by Department Q totaled 48,000, computed as follows: beginning inventory, 5,000 equivalent units; units started and completed in May, 37,000 equivalent units; and ending inventory, 6,000 equivalent units.

Refer to the information above. Assuming that the cost of direct materials used by Department Q in May was $440,000, the materials cost assigned to unfinished units at May 31 would be: Do not round intermediate calculations

$55,000.

$26,400.

$70,400.

Impossible to determine unless we know the percentage of completion for ending inventory units.
