As in the previous problem, Hallie manufactures and sells three models of laptop computers. The company sells approximately 40% of the premium model, 27% of the platinum model, and 33% of the business model. Sales and cost data is below: In the previous problem, you calculated the weighted-average contribution margin (in units) for this sales mix, and rounded it to the nearest cent. Assume that Hallie has $255,474 in fixed costs. Using this information, calculate the total break-even sales in units. (Enter your answer rounded to the nearest whole number.)
