See a solution process below:

Explanation:

We can rewrite Part A of the question as:

What is 6% of $85.25?

"Percent" or "%" means "out of 100" or "per 100", Therefore 6% can be written as #6/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the amount of tax we are looking for "x".

Putting this altogether we can write this equation and solve for #x# while keeping the equation balanced:

#x = 6/100 xx $85.25#

#x = ($511.50)/100#

#x = $5.1150#

Or

#$5.12# rounded to the nearest sent.

We can also rewrite Part B of the question as:

What is 18% of $85.25?

You can use the same process as for Part A to solve Part B,
