Including a 9% sales tax, an inn charges $153.69 per night. Find the inn's nightly cost before tax is added. Please help

$139.86

Step-by-step explanation:

First, change 9% to a decimal

9% to 0.09

Then times the night cost and tax

153.69 x 0.09 = 13.8321

Make sure to round the result to the hundredths place.

So,

$13.83 is our sales tax.

Now subtract the night cost and the sales tax

153.69 - 13.83 = 139.86

139.86 is the nightly cost

6(h+1)/2=a

a=area

step-by-step explanation:
