Solution Summary: The author explains the function representing the total amount of property tax for a home based on the taxable value of x thousand dollars.
The millage rate is the amount of property tax per
$1000
of the taxable value of a home. For a certain county the millage rate is 24 mil (
$24
in tax per
$1000
of taxable value of the home). A city within the county also imposes a flat fee of
$108
per home.
