Madhu Patel is a sales analyst for Four Winds Energy, a manufacturer of wind energy products, in San Antonio, Texas. Madhu is developing a workbook to analyze the profitability of the company's wind turbines. She asks you to help her analyze the sales data to determine how the company can increase profits.

Go to the Income Analysis worksheet, which lists the revenue and expenses for the Boreas wind turbine and calculates the net income. Madhu wants to compare the financial outcomes for varying amounts of turbines sold and identify the number of units the company needs to sell to break even. Madhu has already entered formulas in the range E5:H5 to extract data from the income analysis in the range B4:C26. In the range E5:H14, create one-variable data table using cell C5 as the Column input cell, to calculate the revenue, expenses, and net income based on units sold.
