watermelons in baskets

Question

Tiffany buys a basket of watermelons on sale for $9 before tax. The sales tax is 9% What is the total price Tiffany pays for the basket of watermelons

Answer 1

$9 * 1.09 = x

Because the has to pay the 9 dollars, plus 9% (or .09) for tax.

x = 9.81

You can also think of it this way.

$9 * .09 = $0.81

So she is paying $0.81 for tax. Then add that on to the $9 she is paying for the watermelon and the total amount she would pay is $9.81.
