Final answer:
To determine the number of units the firm should produce for the coming month, calculate the desired ending inventory by multiplying the predicted sales by the desired ending inventory percentage and subtract the beginning inventory from the desired ending inventory.
Step-by-step explanation:
To determine the number of units the firm should produce for the coming month, we need to calculate the desired ending inventory and subtract it from the predicted sales. The desired ending inventory is calculated by multiplying the predicted sales by the desired ending inventory percentage, which is 10%. The calculation is as follows:
Desired ending inventory = 5,500 x 0.10 = 550 units
We then subtract the beginning inventory of 400 units from the desired ending inventory to get the number of units that need to be produced:
Number of units to produce = Desired ending inventory - Beginning inventory = 550 - 400 = 150 units
