Answer:
450,000 units
Explanation:
This question asks to calculate the equivalent units of materials. It must be known that equivalent units are calculated by multiplying the number of physical units by percentage of completion.
The question assumes that materials are entered at the beginning of the process.
Mathematically, the equivalent units for materials = started into production + Beginning work in process
= 25,000 units + 425,000 units = 450,000 units
