Step-by-step explanation:
we know that
The equation of a exponential growth is equal to

where
y ----> is the population
x ---> is the number of years since now
a ---> is the initial value or y-intercept
r ---> is the rate of change
we have


substitute


For y=19,600
substitute in the exponential equation and solve for x


apply log booth sides
