Express Delivery is a rapidly growing delivery service. Last year,80% of its revenue came from the delivery of mailing pouches and small, standardized delivery boxes (which provides a20% contribution margin). The other20% of its revenue came from delivering non-standardized boxes (which provides a70% contribution margin). With the rapid growth of Internet retail sales, Express believes that there are great opportunities for growth in the delivery of non-standardized boxes. The company has fixed costs of $13,350,000. (a)What is the companys break-even point in total sales dollars?

(b)The companys management would like to hold its fixed costs constant but shift its sales mix so that60% of its revenue comes from the delivery of non-standardized boxes and the remainder from pouches and small boxes. If this were to occur, what would be the companys break-even sales, and what amount of sales would be provided by each service type?(Use Weighted-Average Contribution Margin Ratio rounded to 4 decimal places e.g. 0.2552 and round final answers to 0 decimal places, e.g. 2,510.)
