I need detailed help with steps on how to solve :

SmoothIt Inc is facing a problem with their 4th quarter absorption costing net operating income on December 23rd. The net operating income target is $2,000,000 and the data so far is as follows :

Sales Revenue : $25,000,000 ($500 per unit)

Variable Cost of Goods Sold : $10,000,000 ($200 per unit )

Fixed Overhead : $12,000,000

Fixed Selling and Adminstrative : $2,000,000

Variable Selling and Admin : 4% commission on sales

SmoothIt has a policy of having 0 inventories at the end of each quarter. No further sales are possible during the year and all the units that have been produced so far have been sold. The CEO is planning to produce items for inventory to meet net operating income target .

Question : How many units need to be produced for inventory to meet net operating income target if sales commission is left unchanged at 4% ?

A) 4,054 B) 30,000 C) 10,000 D) 15,000 E) None

Thanks!
