I want you to build a leverage problem. please use 10% as the loan rate to help me out in the grading. I want you to make up all the sales and expense information you will need to produce ratios for:Gross MarginProfit MarginReturn on AssetsReturn on Shareholder equityDebt to equity ratioI want you to then increase sales by 25% and decrease sales by 25% and show the impact on the above ratios. You need to write the problem so that the company goes from profitability to being unprofitable when sales drop 25%. I want you to also write a narrative to your problem. Write the narrative as if you were teaching another student how to work through the problem for an up coming exam.
