What is .5% of $40,000?

Quick way of working stuff out like this is to work out 10% then 1% then 0.5%.

To do ten percent move the decimal place one spot to the left, so:

$40000 becomes $4000.0 (or $4000)

To get one percent, it's two spots, so:

$400.00 (or $400).

Now you want 0.5% (half of one percent, just take half of $400).

So your answer is $200.
