The consumption of tungsten (in metric tons) in a country is given approximately by $$p(t) = 140t^2 + 1,072t + 14,913$$ 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 2025 and the instantaneous rate of change of consumption in 2025, and write a brief verbal interpretation of these results. (A) p'(t) =
