Question

The property taxes in a town decrease as the distance from the local elementary school increases. The greatest property taxes are 4.5%, and for every 10 miles from the school, property taxes decrease by 0.5 percentage points. If a house's property taxes are 3%, percent, what is the distance of that house from the school?
A. 10 miles

B. 20 miles

C. 30 miles

D. 40 miles

Answer 1

30 miles, every 10 miles the percent drops .5%

We can set this equation up:
3 + .5x = 4.5

Subtract 3 from each side.
.5x = 1.5
x = 3
 
We multiply this by 10 since we factored it in the beginning.

We get 30.
