Answer:
68,000 units
Explanation:
The computation of the number of units that produced in september is given below;
The sales units at September is
= $400,000 ÷ 5
= 80,000 units
And, the october sales units is
= $320,000 ÷ 5
= 64,000 units
So, the production should be
= Ending finished units + sales units - beginning finished units
= (25% of 64,000 units) + 80,000 units - 28,000 units
= 16,000 units + 80,000 units - 28,000 units
= 68,000 units
