Question

Sue bought a new dress while on holiday in the USA. The sales tax was 8%. If she paid

$6.40 tax, and if she was also charged 15% duty on the original purchase (before tax),
how much did she pay in all?

Answer 1

Sue paid $98.40 in all.

Explanation:

Let the original price of the dress be $x.

The amount of tax Sue paid is $6.40, which is 8% of the original price, so:

0.08x = $6.40

Solving for x:

x = $6.40 / 0.08 = $80

Sue was charged 15% duty on the original price, which is:

0.15($80) = $12

So the total cost of the dress, including tax and duty, is:

$80 + $6.40 + $12 = $98.40
