Question

Please help look at link to view problem

Answer 1

plug in 100, 200, and 400 for P(t) and solve for t each time

Answer 2

100=40e^(.02*t)

2.5=e^(.02*t)

ln(2.5)=ln(e^(.02t)

.91629=.02*t

t=45.8 years since 1990

so the population will be at 100 million in 2035

repeat this for P(t)=200 and 400
