Balance lottery sales

First time on this forum, looking for help with Excel. I own a small business and we sell lottery tickets. At the end of the day I use Excel to balance our lottery sales. The formula I have created in Excel works but is a bit cumbersome. I was looking for a better way to enter book numbers and have the worksheet calculate the $ that should be in the register. I currently have 3 lines of formulas that are all IF statements. The problem with this is that we constantly get new books in and if we get a new $10 book and I need to shift a few books around to get it in the cases near the other $10 books I have to completely redo the worksheet. I'm wondering if there is better way to do this in Excel. I tried to look at Excel tutorials and other help references but just can't seem to find a figure it out. I have been using this spreadsheet for so long I just can't think of another way to do it. I'm okay with Excel but I'm sure i only use a small percentage of it's features to begin with. Any help would be greatly appreciated.

I have attached a small section of the spreadsheet I am currently using. Red numbers are formulas and black numbers are the numbers we enter into the worksheet.
