The consumption of tungsten (in metric tons) in a country is given approximately by p(t) = 137t + 1,072t + 14,913, where t is time in years and t= 0 corresponds to 2010. (A) Use the four-step process to find p'(t). (B) Find the annual consumption in 2030 and the instantaneous rate of change of consumption in 2030, and write a brief verbal interpretation of these results
