Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
Maurice can make 20 burgers because 4 times 5 equals <<4*5=20>>20.
Maurice can invite 19 people because 20 minus 1 equals <<20-1=19>>19.
#### 19
