Your house recently was infested with a type of killer bee from Africa and you are forced to evacuate. There were 3,000 bees in the siding of your wall. A local company came and
treated your house and told you that approximately 18.5% of the bees would die each day.
When there are fewer than 500 bees in your siding, you can return to your home.
Approximately how long will it be before you can return?
