Please try to find a realgrowth ratefor your state and city. If you cant find the city rate please use any number other than .9%.REMINDER: How to solve equation with exponentsWe have to solve equation for theannual growth rateof .9%2 = 1.009^n where we need to calculate n. To solve exponential equation we need to take log of both parts.log(2) = log(1.009^n)we use the following rule:log(m^r) = r * log(m ) the log of m with an exponent r is r times the log of mso log(1.009^n) = n*log(1.009)Usingcalculator: log2 =0.30103 and log 1.009 = 0.003891so0.30103 = n * 0.003891n = 0.30103 / 0.003891n = 77.36242n = 77.4Hint: if base of log is not defined then by default the base is 10. If you use Excel you calculate log(210) and log (1.00910).
