Colorworks sells each carton of calendars for $4.15. Required 1. Use the income statement equation approach to compute the number of cartons of cal- endars Colorworks must sell each month to break even. 2. Use the contribution margin ratio CVP formula to compute the dollar amount of monthly sales Colorworks needs to earn $35,000 in operating income. 3. Prepare Colorworks' contribution margin income statement for June for sales of 450,000 cartons of calendars. Cost of goods sold is 70% of variable expenses. Operating expenses make up the rest of the variable expenses and all of the fixed expenses. 4. The company is considering an expansion that will increase fixed expenses by 40% and variable expenses by one-third. Compute the new breakeven point in units and in dollars.
