The following budgeted information relates to a manufacturing company for the next period:

Sales 12,000 Units

Fixed Production Cost : $63,000
Fixed Selling Cost : $12,000

Normal level of activity is 14,000 units per period.
Using absorption costing the profit has been calculated as $36,000

Find the profit using marginal costing.

Can someone help?

Thanks
