Please, I need help with the calculation below as I am stumped.

Davis Corporation uses the weighted-average method in its process costing system. This month, the beginning inventory in the first processing department consisted of 400 units. The costs and percentage completion of these units in beginning inventory were:

Cost Percent Complete

Material Costs 7,500 75%

Conversion costs 4,999 45%

The cost per equivalent unit for materials for the month in the first processing department is?
