Andy had 1/2 as much money as Brenda. Brenda had 1/2 as much money as Cathy. If Cathy has $78 more than Andy, how much money did they have altogether?

We can write everything in terms of x, the number of money Cathy has.

Cathy = x

Brenda = x/2

Andy = (x/2)/2 = x/4

x = x/4 + 78

3x/4 = 78

x = 104

So, Cathy has $104, Brenda has $52, and Andy has $26. In total, they have **$182.**
