Answer:
15.035 years
Step-by-step explanation:
The exponential function to calculate population growth is
P(t) = Poe^kt
P(t) = Population size after t years = 3.6 million
Po = Initial population size = 2.1 million
k = growth rate = 3.65% = 0.0365
t = time in years = ???
Hence:
3600000 = 2100000 × e ^0.0365t
Divide both sides by 2100000
3600000/2100000 = e^0.0365t
1.7142857143 = e^0.0365t
Find the log of both sides
Log 1.7142857143 = log (e^0.0365t)
Log 1.7142857143 /Log 0.0365 = t
t = 15.035 years

Hoi!
Here's how you would write this.
z - 34.7 = 68.2
"Less than" indicates subtraction, but from what? "Less than z", so we're subtracting something from z. If you look at the equation, how would we calculate 34.7 less than z? To do this, we would subtract 34.7 from z. Since we're given our answer to the equation, just slap that into the equation after an "equals" symbol, and you're finished!
