A$78.00 pair of shoes cost $84.63 after tax is added. what percentage of the cost is tax?
a) 8.0%
b) 8.25%
c) 8.5%
d) 8.75%

C) 8.5%

Step-by-step explanation:

First, subtract the cost after tax to the cost before tax.

84.63 - 78.00 =

6.63

Then, divide the original cost from this

6.63 / 78.00 =

0.085

When reading percentages on a calculator, we know this is equivalent to 8.5%

Hope this helps! :)
