debra buys a new mountain bike for 750 dollars . Sales tax is 9% . how much does Debra actually have to pay ?

Georgia [21]

Answer:

$817.50

Step-by-step explanation:

Hello Matt7151!

To find the total amount, we will first need to find how much tax.

We can express 9% as the fraction $\frac{9}{100}$ .

$\frac{9}{100}$ × 750 = 67.50

So she's paying $67.50 sales tax.

750.00

67.50

-------------------

817.50

So Debra's really paying $817.50.

Thus, the answer is $\boxed{$817.50}$$ $\boxed{817.50}$ .
