<PRE><B>Question 44797</B>
The mythical town of Alphaville had a population of 10,000 people in 1930. Since then, the population has doubled every 23 years. (For example in 1953, the population equalled 20,000; in 1976 it was 40,000; in 1999, it was 80,000 and so on).
What was the population in 1980?

The equation for this is
population = 10000*2^[(x-1930)/23]
where x is the year you are interested in.

When x=1980 the population is 45125
