Question: On Monday Elisa paints 30 square feet of her house's walls. On Tuesday she paints twice that amount. On Wednesday she finishes up by painting half as many square feet as she painted on Monday. How many square feet total does Elisa paint in her house?

[Question]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?
[Answer]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. The answer is 9.
