Need help getting the answers and rounding to 1 decimal place after the whole number.

Perform a horizontal analysis, showing the percentage change in each income statement component between 2014 and 2015. (Negative answers should be indicated by a minus sign. Round your answers to 1 decimal place, (i.e., .234 should be entered as 23.4).) Perform a vertical analysis, showing each income statement component as a percent of sales for each year. (Percentages may not add exactly due to rounding. Round your answers to 1 decimal place, (i.e., .234 should be entered as 23.4).)
