Operating expenses consist of $30,000 of variable costs and $70,000 of fixed costs. Required: A. Calculate the contribution margin and the contribution margin ratio. B. Calculate the break-even point in units and sales dollars. C. Calculate the safety margin (in dollars) D. Calculate the degree of operating leverage, and use it to calculate the percent increase in income that would result from a 20% increase in sales. E. PowerClean received an order for 6,000 units at a price of $25.00. There will be no increase in fixed costs, but variable costs will be reduced by $0.54 per unit because of cheaper packaging. Determine the projected increase or decrease in profit from the order, assuming there are no opportunity costs
