A man went to the hardware store to buy items for his house. 1 would cost $.25. 12 would cost $.50. 122 would cost $.75. When he left the store he had spent $.75, what did he buy?
The man bought house numbers. The reasoning behind this is that the cost of each item represents the number of digits in the item: 1 digit costs $.25, 2 digits cost $.50, and 3 digits cost $.75.
