Figuring a contribution format income statement
I want to know how to develop a contribution format income statement, given only part of the needed information. The info is as follows:
Quarter1 Quarter2 Quarter3
Net sales 44116 33836
Cost of sales 34429 33836
Gross profit 9687 9990
Sell. Gen/admin
Expenses 6123 6184
Operating income 3564 3806
Required:
Prepare a contribution format income statement for the third quarter assuming that the company's net sales were 45,500 and its cost of sales as a percentage of net sales remained unchanged from the prior quarter.
I need some assistance with this problem. Thank you.
