Answer: House numbers (decals)
Typical guesses include nuts, bolts, nails, washers, etc. Actually, the 1 is made up of one digit, 50 is made up of two digits, and 200 is made up of three digits. Each digit (decal) costs $1. Therefore, if your house number is 200, then you would need three digits, which would cost $3.
