why the difference in final sales

Hi

I am really new to selling and I'm after some help.

My monthly sales figure is different from my sold amount.

One says January activity amount (wait for it) $43.62c

And the sold part say's $43.34c 

The difference is only 28 cents but shouldn't they be the same?

Like I said I'm really new to selling more of a hobby with my daughter so any help would be great.

Thanks Dad
