The bat and the ball…

A classic from Behavioral Economics:
“A bat and a ball together cost 1.10$. The bat costs 1$ more than the ball. How much does the ball cost?”

The BE-guys have found that most people get this wrong.

For the mathematically inclined: a simple equation system with two variables will solve the problem:

x + y = 1.10

x – y = 1.00
