According to my employee contract because I am casual I am being paid with an extra 20% loading making my total being $22/h.
I wanted to work out how much I would normally have been paid if I wasn't a causal so I did
$(\frac{22}{100}) \times 20$
This would equal I am being paid an extra \$4.4 making my original pay $17.6/h. But then it hit me that this wouldn't be right because it would mean my current pay is 100% not 120% and I just worked out what 80% is.
The only other way I could try and work this out is going through every number between 1 and 22, getting what 1% is, multiplying that by 10 and adding it to my original number and checking if it was 22. To do that quickly I would have to write a program but there has to be a better way than going though every number.
So given how my pay of $22/h is 120% how can I work out what 100% is?
Let the amount you would be getting paid be $x$
Then: $x+.20x=22$ so $x=(22)/(1+.20)=18.33$. You get paid $3.67$ more.
