At first, F***y and Grace had $306 altogether. After F***y spent 1/5 of her money and Grace spent $72, both of them had the same amount of money left. How much money did F***y have at first?

Answer: F***y (is that just me or does it look like that for everyone?) had 130 at first. 

 

Solution:

Let F be the amount of money F***y (I can't begin to imagine what goes there) has. Let G be the number of money Grace has.

 

F + G = 306

4/5 * F = G - 72

 

I'll solve this system using substitution.

 

G = 306 - F

4/5 * F = 306 - F - 72

4/5 * F = 234 - F

9/5 * F = 234

F = 130
