As a clarifier, I'm a 21 year old woman and my boyfriend of six months is 27. I am on birth control. Sorry if this sounds crude.

A cash drawer contains only fives and twenties. There are eight more fives than twenties. The total value of the money is $215. How many of each type of bill are there?
....
I set it up as:
5a + 20b = 215
a + b = 215
but that can't be right... help?
