Population Decay Difficult Due to a warming climate, the population of cave crickets throughout the United States is decreasing exponentially every year. The population can be modeled using:
P(t) = A(r)ᵗ
Scientists started measuring in the year 2011 and found the total population to be 140,000, when they measured again in 2012 they found the population to be 35,000. Assuming the exponential rate of decrease remains the same, what is the first year that the population is less than 1,000?
