Let's start with your hourly pay of $10.
We want to subtract 7.65%, 12% and 8% --> 27.65%
$10 x 27.65%
= $2.765 per hour deducted
So your remaining pay is:
$10 - $2.765
= $7.235
Divide that into $800 to figure out how many hours you'll have to work.
800 / 7.235
= 110.5736 hours
Answer:
About 111 hours
