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?
There were 1+2+3=<<1+2+3=6>>6 people at the house
That means they use 6*2=<<6*2=12>>12 plates per meal
So they use 12*3=<<12*3=36>>36 plates per day
That means they use 36*4=<<36*4=144>>144 plates for the visit
