Since it is Maurice's turn to host this year’s neighborhood cookout, he goes to the local wholesale club to buy ground beef. The wholesale club sells ground beef in 5-pound packages. Maurice wants to make one 2-pound burger for each person that attends, so he purchases 4 packages of ground beef. How many people can Maurice invite to the cookout so that everybody, including himself, gets a burger? Think carefully first, then make a decision:

Maurice buys 4 * 5 = 20 pounds of ground beef. If 2 pounds of ground beef make a burger, then he can make 20 / 2 = 10 burgers. Given that Maurice will have 1 burger, he can invite 10 - 1 = 9 people. So, the answer is 9.
