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 [tex]\frac{9}{100}[/tex].
[tex]\frac{9}{100}[/tex] × 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 [tex]\boxed{$817.50}$[/tex][tex]$\boxed{817.50}$[/tex].
