Answer 1

Given that the basket of watermelons sells for $9 before tax and the tax rate is 9%.

The tax on the basket of watermelons is given by

$\frac{9\%}{100\%} \times\ 9=0.09\times\ 9 \\ \\ =\ 0.81$

Therefore, the total price Tiffany pays for the basket of watermelons is $9 + $0.81 = $9.81

Answer 2

Let x be the total price of basket of watermelons including tax.

We have been given that Tiffany buys a of basket of watermelons on sale for $9. The sales tax is 9%. So our total price will be 9 plus 9% of cost of watermelons' basket ($9).

$x=9+ (9 \times \frac{9}{100})$    

$x=9+ (9 \times 0.09)$                  

$x=9+ (0.81)$

$x=9+0.81=9.81$

Therefore, Tiffany will pay $9.81 for the basket of watermelons.
