# Beginner needs help!

This is for work, so I'm incredibly nervous about it. I have a list of about 20 product prices.
When I'm balancing paperwork, I need to know what prices combined together make up a specific price. For instance, I have a difference of $5.12 after I balance, I need to know what makes up the$5.12. Of my 20 prices one of the combinations makes $5.12...$1.76, 2.04, and 1.32..
But it takes FOREVER to figure out what the combination is.
I would REALLY appreciate anyone's help or thoughts ! Jennifer
