Isha is at an arcade. There is a base fee of $6 to enter the game room. Every game costs $0.4 or 40 cents to play. If Isha ends up spending $56 at the arcade, how many games did she play?
An explanation:
The base fee of $6 represents the constant 6 in the equation. Every game costs $0.4, which equals 2/5.
Hope this helps! If you don't like this one I might be able to think of another one :)
