heather is buying a tshirt for $8. sales tax is 8 1/4 cents per dollar. how much will heather pay in sales tax on her purchase?
a)$0.0825
b)$0.33
c)$0.50
D)$0.66
e)$0.75

Multiply:
8 x .0825 = ?? 
the answer to that question is .66

8 1/4 cents is $.0825.
Multiply $.0825 by $8. What answer do you get? 
i got 0.0825

0.0825 is how you express the tax percentage in the problem. Multiply that number by 8 to find out how much tax she paid.
How much do you get? It's not 0.0825!
=) 
i got 0.66

Good  $0.66 is correct.

Q: well how did you get 81/4 to .0825?
