The first time we did it, my co-worker couldn't solve it herself but insisted that my answer had to be wrong because I did it too fast because apparently the rest of my department took over a half hour to solve it (their answers were wrong by the way).

The second time I was critiqued for not showing all of my work . We have yet to do one where I haven't had to explain how to get the correct answer to at least one person.

I know I sound really bitchy and condescending. I fully acknowledge that not everyone is good at math and I'm totally okay with that there are lots of things I can't remember from school. The thing is all of these people work in my department - the

**ACCOUNTING**

**DEPARTMENT!!!**They are paid to work with numbers all day and should not look at me oddly because I remember how to do simple algebra!!!

So here's the problem. Feel free to post your answers in the comments.

A magic money box doubles any money put into it and then adds $1. Kara put some money in the box and the box did its magic. She then took this new amount of money and put it back in the box again. After the box did its magic again, Kara took of $31. How much money did Kara originally put into the magic money box?

2x+1=31

2x=31-1

2x=30

x=15

She put in $15.

How did I do?

Shall I challenge my accounting office friends to see if they can do it?

Whoops - missed a repeat!

The answer is 7.

I guess I need to read the question better!

I got 7 as well (before seeing LS's answer). But then, we're smart people.
