Question

A pair of shoes usually sells for $64. If the shoes are 20% off, and sales tax is 5%, what is the total price of the shoes, including tax?

Answer 1

Well 20% of $64 is $12.80.
Since it's a sale, you'd subtract 20% ($12.80) from the base price ($64).
$64 - $12.80 is $51.20.
But we need to add sales tax, which is 5% of the new price ($51.20)
5% of $51.20 is $2.56.
Since it's tax, you would add it to the total price.
$51.20 + $2.56 is $52.76.

So there's your answer: $52.76.
