Calculate the operating breakeven point in units. Calculate the firm's EBIT at 13,000, 14,000, and 15,000 units, respectively. With 14,000 units as a base, what are the percentage changes in units sold and EBIT as sales move from the base to the other sales levels used in pan (b)? Use the percentages computed in pan (c) to determine the degree of operating leverage (DOL). Use the formula for degree of operating leverage to determine the DOL at 14.000 units The operating breakeven point is The EBIT for the 13,000 units level is The EBIT for the 14,000 units level is The EBIT for the 15,000 units level is With 14,000 units as a base, the change in sales as a percentage for the 13,000 units level is With 14,000 units as a base, the change in sales as a percentage for the 15,000 units level is With 14,000 units as a base, the change in EBIT as a percentage for the 13,000 units level is With 14,000 units as a base, the change in EBIT as a percentage for the 15.000 units level is The degree of operating leverage for the 13,000 units level is The degree of operating leverage for the 15,000 units level is The degree of operating leverage for the 14,000 units level is
