Rate of decay question? (1 Viewer)

[timeslowsdown]

Just a simple question I don't know how to do. Please explain:

The annual population of a country is increasing at a rate of 6.9%, that is, dP/dt = 0.069P. If the population is 50,000 in 2015, find
a) a formula for the population growth
b) the rate at which the population will be growing in the year 2020

Thank you!

turn ,dp/dt=0.069p, upside down, so its now dt/dp=1/(0.069p), than integrate so t=integral:1/(0.069p) dp. keep going from there.If you still cant do it ill post up the rest.
