I am having trouble finding the Weighted Average(cost of goods) and the LIFO (cost of goods)on a income statement.

1. Complete comparative income statements for the month of January for Laker Company for the four inventory methods. Assume expenses are $1,250, and that the applicable income tax rate is 40% (Round your average cost per unit to 2 decimal places.) I am having a hard time figuring the cost of good sold and the income tax expense for the Weighted Average and LIFO.
