what is ur question on the question?

anonymous · Answer

i dong know how to set it up

anonymous · Answer

ok,
Including 5% sales tax, an inn charges $210.00 per night.
means 5%*x + x = $210.00

anonymous · Answer

how do i get the last part. don't i just divide .05 into 210.00

anonymous · Answer

close!
we do want to isolate and solve for x, but we need to do it in the right order. 
this equation 
5%*x + x = $210.00
can be rewritten as
0.5x + x =210
so combine like terms, then divide.

anonymous · Answer

would it be 1.5x when added together

anonymous · Answer

yep, 
so what does x equal?
