Answer:
Total equivalent units of materials =67,000 units
Explanation:
Equivalent unit is computed as follows:
Equivalent units =Degree of completion × units of inventory
Fully worked = 67,000-6,700= 60,300
Closing inventory  = 6,700
Item                        Equivalent unit
Fully worked   100%× 60,300=  60,300 units
Closing inventory =  100%× 6,700= 6,700 units
Total equivalent units            67,000 units
Note that we used 100% as the degree of completion for materials because materials  required are always added at the beginning of the process
