en poured into molds to produce the castings. On May 1, there were 900 pounds of alloy in process, which were 40% complete as to conversion. The Work in Process balance for these 900 pounds was $102,960, determined as follows:
Direct materials (900 x $110) $99,000
Conversion (900 x 40% x $11) 3,960
$102,960
