An investment banker is analyzing two companies that specialize in the production and sale of candied yams. Sheridan Yams uses a labor-intensive approach, and Sunland Yams uses a mechanized system. CVP income statements for the two companies are shown below. The investment banker is interested in acquiring one of these companies. However, she is concerned about the impact that each company's cost structure might have on its profitability. Determine the effect on each company's net income if sales decrease by 15% and if sales increase by 10%. Assume that sales fluctuations are attributable to changes in units sold. Do not prepare income statements. (Round answers to 2 decimal places, e.g. 10.52. If % change is negative, enter amount with either a negative sign or parenthesis, es. -10.52 or (10.52).)
