As part of the marketing campaign, EML produced a video tape sales presentation to send to both owners of current EML four-wheel-drive vehicles as well as to owners of four-wheel- drive sports utility vehicles offered by competitors, EML refers to these two target markets as the current customer market and the new customer market. Individuals who receive the new promotion video will also receive a coupon for a test drive of the new EML model for one weekend.

EML estimates that the response rate for the current customer market is 25% and the re- sponse rate for the new customer market is 20%. For the customers who test drive the new model, the sales rate is the percentage of individuals that make a purchase. Marketing re- search studies indicate that the sales rate is 12% for the current customer market and 20% for the new customer market.

In addition, the number of current customers who test drive the new vehicle must be at least twice the number of new customers who test drive the new vehicle.If the marketing budget, excluding test drive costs, is $1.2 million, how many promotions should be sent to each group of customers in order to maximize total sales?
