LAST ATTEMPT!!! Help pls

The Nash Co. knows that students want new backpack and jacket styles before school begins each year. The company is up to the challenge, as its designers and manufacturers work around the clock to create the trendiest looks in both of these product categories. The Nash's top-selling backpack normally brings in a whopping $84 in sales to the business, while its up-and-coming windbreaker jacket sells for a more affordable $56. The company is trying to really push these products, as it earns very high margins on them. In order to capture the hearts and minds of the back-to-school crowd, The Nash management offers a special: buy both a backpack and a jacket for just \$104! Managers hope this hot deal will be attractive to students, particularly since the company's high-end backpack sells for $105 all by itself. If the incremental method is used, what amount of sales will be recorded for each product? (The backpack is considered the primary revenue generator.)
