My question is: Tom invites his parents and 3 siblings to his house. They each eat 3 times a day. How many plates do Tom and his guests use while they are there for the 4 days if each person uses 2 plates per meal? Your thoughts:
There were 1 + 2 + 3 = 6 people at the house. That means they use 6 * 2 = 12 plates per meal. So they use 12 * 3 = 36 plates per day. That means they use 36 * 4 = 144 plates for the visit. The final answer: 144.
