Question

The state income tax in Connecticut is modeled by the function below, where x is income in dollars. Suppose that Connecticut decided to increase its tax rates by 20% and add a filing fee of $100. Write a function for the new state income tax.
f(x) = {0.02 x   if 0<x<= 10,000
          {0.05x    if x>10,000

anonymous · Answer

f(x) = {0.02(1.02) x +100   if 0<x<= 10,000
          {0.05(1.02)x  +100  if x>10,000
