You have an electric car that you want to use to transport some batteries 1,000 miles. You have 3,000 batteries, but your car can only carry 1,000 of them at once. In addition, for each mile that it travels, the car will need to use up one battery in order to power itself.

How many unspent batteries will you be able to transfer to your destination?

in first thought, one might assume that since you only have 1000 batteries, and you must travel 1000 miles using up one battery per mile, you would reach your destination on you last battery, therefore having no unspent batteries left. but you must also consider the fact that the car most likely has a battery in it already, so you will end up delivering one unspent battery.
