Millage rate is the amount per $1000 that is often used to calculate property tax. For example, a home with a $60,000 taxable value in a municipality with a 19 mil tax rate would require (0.019)($60,000) 5 $1140 in property taxes. In one county, homeowners pay a flat tax of $172 plus a rate of 19 mil on the taxable value of a home.
a. Write a linear function that represents the total property tax T(x) for a home with a taxable value of x dollars.
b. Evaluate T(80,000) and interpret the meaning in the context of this problem
T(x) = mils * taxable value / 1000
T(x) = 19 * x /1000
T(x) = 0.019 x
T(80,000) = 0.019 * 80,000 = $1520
19 mils means a property tax of $19 for every $1000.
Then, for tax value of $80 000, property tax = 80000*19/1000 = $1520
