The columns of the grid
| # | the row number |
| a1 | how many times (amount) the price was paid |
| price | the price of something |
| -% | possible rebate that will be deducted from price |
| a2 | items received for money paid (a1*price)*(1-(%/100)) |
| unit | size of the unit |
| p/u | price of one unit (with size=1) |
Examples
pay 1$ and get 1 item with size 1
pay 2 times 1$ and get 2 items with size 1
pay 2$ and get 2 items with size 1
pay 1$ and get 2 items with size 1 = one for free
original price 1$ with 20% rebatt and get 1 item with size 1 = pay 0.80 $
pay 1$ and get 1 item with size 0.5 = an item with size 1 would cost 2$
