Wallet is the full 100%, so pen is 80%.
This is because the pen cost 20% less THAN the wallet. The thing which is listed after the word “than” is the reference item which we always set to 100%, because you are making comparisons of an item to another already existing item.
Let wallet = 5 units and pen = 4 units.
9 units = $99
1 unit = $11
4 units = $44
5 units = $55
Pen is $44.
Wallet is $55.
