In order to join a dancing club, there is a $30 startup fee and a $4 monthly fee. If you want to spend 1 year in the club, how much money did you spend?

Answer: $78

How?

Well let's first start off with the fee. It's $30, so lets add that to our total.

There are 12 months in a year, and $4 each month to stay in the club.

So 12 x 4 = 48

Then add the startup fee, $30, and you get a total of $78
