Best ResponseYou've already chosen the best response.1No  i think as the principal is decreasing Rate of change = 10082 = 18% Not absolutely sure though

Best ResponseYou've already chosen the best response.0the prob is not clear: "rate of change" is not uniform for an exponential function... http://www.regentsprep.org/regents/math/algebra/AE7/ExpDecayL.htm if it is asking for "growth rate", then @welshfella is right on 18%.

Best ResponseYou've already chosen the best response.0And if it's not asking for "growth rate" then would the answer be different?
