Math Problem Statement
After a ten year study we find that two towns, A and B, have populations modeled by f(x)=-350x+20,000 and f(x)=250x+10,000 respectively, where x is the current year. For what years will the population of town B be greater than the population of town A? (Numbers may be rounded to 2 decimal places.)

f_A(x) = -350x + 20,000
f_B(x) = 250x + 10,000
Set inequality: 250x + 10,000 > -350x + 20,000
