I am looking for C...
my mind is drawing a blank :( lol

8000000=6490000e^.0197t ?

Answer 1

`y = 6.49e^(0.0197t)`

We know that y = 8. So we will plug in 8 for y and solve for t.
`8 = 6.49e^(0.0197t) \\ (8)/(6.49) = e^(0.0197t) \\ 1.232 = e^(0.0197t) \\ ln (1.232) = ln(e^(0.0197t)) \\ 0.2092 = 0.0197t \\ t = (0.2092)/(0.0197) = 10.6`

You can say that the population will reach 8 million in about 10.6 years (or 11 if they want it rounded).
