Goodsprings has a tax base of $90,000,000 and a budget of $1,100,000. What is the tax rate in terms of mills?

Answer 1

The tax rate needed to balance the budget will be ...
  tax rate = (budget amount)/(tax base)
In millions*, this is
  tax rate = 1.1/90 = 0.0122... ≈ 12.2/1000 = 12.2‰

In terms of mils, the tax rate is 12.2.

_____
* As long as numerator and denominator are both expressed in millions, the factor of 1 million cancels from numerator and denominator and the fraction is the same value it would be if we put in all those zeros.
