Question

5. An economy's consumer price index (CPI) is described by: I(t) = -0.05t^3 + 0.5t^2 + 50 (0 ? t ? 9) where t is measured in years, with t = 0 corresponding to the beginning of 2010. a. Find the annual percentage rate of inflation in the CPI (inflation rate) of the country at the beginning of 2016 (t = 6). b. Show that inflation was moderating (slowing) at the beginning of 2016 (t = 6).

Step 1

This will give us the rate of change of the CPI, which represents the inflation rate. The given function is: I(t) = 0.05t^3 + 0.5t^2 + 50 Now, let's find the derivative of I(t) with respect to t: I'(t) = dI(t)/dt = 0.15t^2 + 1t Now, we need to find the Show more…

An economy's consumer price index (CPI) is described by: I(t) = -0.05t^3 + 0.5t^2 + 50 (0 ≤ t ≤ 9), where t is measured in years, with t = 0 corresponding to the beginning of 2010. a. Find the annual percentage rate of inflation in the CPI (inflation rate) of the country at the beginning of 2016 (t = 6). b. Show that inflation was moderating (slowing) at the beginning of 2016 (t = 6).
