I just want to point out that even though $636.40 is the equivalent of $509 for 32 hours, you will be getting a little less than $636.40 because the amount of taxes taken out will be greater.
(509 / 32) X 40
If it's take home after taxes, the real number will be different.
You'll make 636.22 for 40 hours.
509=32x
divide all by 32
15.90625=x
multiply all by 40
636.25=4x
You make $15.90 per hour (502 divided by 32). $15.90 x 40 hours = $636 gross wages.
509 * (40/32)
about $636.40
