Tiffany buys a basket of watermelons on sale for \$9$9dollar sign, 9 before tax. The sales tax is 9\%9%9, percent.
Gnoma [55]

Answer:

<em>Tiffany pays a total price of $9.81 for the basket of watermelons</em>

Step-by-step explanation:

<u>Percentages</u>

To increase a certain amount by a given percentage, we can first calculate the increasing amount and then add it to the original amount.

If the price of the basket of watermelons was $9 before tax, and the sales tax is 9%, we first calculate the tax amount to pay:

$9 * 9 / 100 = $0.81

Now we add it to $9 to get the total price paid by Tiffany:

Total price = $9 + $0.81 = $9.81

Tiffany pays a total price of $9.81 for the basket of watermelons

Combine like terms to find X<br><br> 7x+=9x-3
blondinia [14]

Answer:x = -1.5

Step-by-step explanation:

Simplifying

7x + -9x = 3

Combine like terms: 7x + -9x = -2x

-2x = 3

Solving

-2x = 3

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '-2'.

x = -1.5

Simplifying

x = -1.5
