Please help me this is due! 7th grade math offering 20 points and might give if I get more than one answer :)

I'm pretty sure it's $98.10

Step-by-step explanation:

$90*.09=8.1

90+8.1=98.1

which can also be written as $98.10

$98.90

Step-by-step explanation:

Let x = original price in dollars

x is the original price

9% of this original price is equal to 0.09x

subtract: x - 0.09x = 0.91x

The discount price is equal to 0.91x and it's equal to 90 dollars, so they must be the same value.

0.91x = 90

0.91x/0.91 = 90/0.91

x = 98.9010989

x = 98.90

So the original price is $98.90

good luck!
