This blog is not just about things I like, I hope it could be a constructive thing that the community finds useful.
Anyway
I have a trick for quickly working out percentages.
To know the percentage of a price I move the decimal place of the percent 2 places then multiply by the price.
5 percent would be Price X 0.05
20 percent would be Price X 0.20
If I wanted to add percent I would add 1.0 to the percentage
Adding 5 percent would be Price X 1.05
Adding 20 percent would be Price X 1.20
If I wanted to subtract a percentage I would take away the percentage from 100 then multiply by the new percent.
Subtracting 5 percent would be Price X 0.95
Subtracting 20 percent would be Price X 0.80
That's it.
