The World Population Clock indicates that the growth rate is declining. It estimates that in 2030 the population will be about 8.5 billion and the growth rate will be about 0.87% per year. Write a new exponential model for P(t), the population t years after 2030. Q = 8.5 (1+ 0.0087 )t

Many scientists believe that the earth can support a maximum human population of about 10 billion people indefinitely without running out of resources. According to your model, in what year will we reach that population?
