A restaurant owner has a luncheon special that consists of a cup of soup, half of a sandwich, and a beverage. She wants to advertise that a different luncheon of three items can be purchased 365 days of the year for $4.99 apiece. If she has 7 different kinds of soup and 6 different kinds of sandwiches, how many different kinds of beverages are needed to provide at least 365 different luncheons?

7 * 6 * n = 365
n = 8.7 so 9
