Math Help Please?

I can't get my mind wrapped around this. If you can, please help me. It's for a reimbursement thing.

Situation: I have a total price, but the tax is not indicated. I need to break out what the tax was and indicate it on my TPS form. (Note that this is not pointless. Just annoying)

The tax rate is 6.75%
The total bill, including tax=$14.66

What is the total tax in dollars/cents?
What then is the bill prior to tax? (I know this will be $14.66-tax)

THANKS mathy people!
