The tax is $5.16

The total price of the stereo is $91.16

Explanation:

The first part of the problem, "What was the tax on the stereo?", can be rewritten as;

What is 6% of $86.00?

"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 tax we are looking for "t".

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

#t = 6/100 xx $86.00#

#t = ($516.00)/100#

#t = $5.16#

The tax is $5.16

The total price is:

#S = p + t#

Where

#S# is the total price of the Stereo
#p# is the price of the stereo - $86.00
#t# is the tax calculated above - #$5.16

#S = $86.00 + $5.16#

#S = $91.16#

The total price of the stereo is $91.16
