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
[tex] \frac{9\%}{100\%} \times\$9=0.09\times\$9 \\ \\ =\$0.81[/tex]
Therefore, the total price Tiffany pays for the basket of watermelons is $9 + $0.81 = $9.81
The tax on the basket of watermelons is given by
[tex] \frac{9\%}{100\%} \times\$9=0.09\times\$9 \\ \\ =\$0.81[/tex]
Therefore, the total price Tiffany pays for the basket of watermelons is $9 + $0.81 = $9.81
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).
[tex]x=9+ (9 \times \frac{9}{100})[/tex]
[tex]x=9+ (9 \times 0.09)[/tex]
[tex]x=9+ (0.81)[/tex]
[tex]x=9+0.81=9.81[/tex]
Therefore, Tiffany will pay $9.81 for the basket of watermelons.
