The equation for the amount of tax (8%) T on an item that costs P dollars is:

T=0.08P

and in case it matters, the cost of the item would be

 

Cost = p + (p x 0.08)

        = p x (1.08)

 

Hi Brittany. 

 

8% as a decimal is 0.08

 

So, tax is just the item cost times the tax rate.  In this case it is:

t = p x 0.08

I hope that helps.
