A camera has a listed price of $665.98 before tax. If the sales tax rate is 9.5%, find the total cost of the camera with sales tax Included. Round your answer to the nearest cent, as necessary.
we know that
100%+9.5%=109.5%=109.5/100=1.095
so
Multiply the listed price of $665.98 by 1.095
$665.98*1.095=$729.25
therefore
the answer is $729.25
