A mailman has to deliver 48 pieces of junk mail. There are 8 houses on the block. 2 of the houses have white mailboxes and 3 have red mailboxes. How many pieces of junk mail will each of those houses get? Let's answer step by step:
The mailman has 48 pieces of junk mail / 8 houses = 6 pieces per house. The houses with white mailboxes get 2 * 6 pieces = 12 pieces of junk mail. The houses with red mailboxes get 3 * 6 pieces = 18 pieces of junk mail. The houses with red and white mailboxes will get a total of 12 + 18 = 30 pieces of junk mail. 30 / 5 = 6 pieces of junk mail each. The answer: 6.
