SOLUTION: I've been trying to answer this question but I don't know how to find b and how to proceed from there. U.S. Population YEAR POPULATION 1930 122,800,000 1940 131,

Question 1147910: I've been trying to answer this question but I don't know how to find b and how to proceed from there.
U.S. Population

YEAR POPULATION
1930 122,800,000
1940 131,700,000
1950 150,700,000
1960 179,300,000

It is estimated that the limiting population that the United States can support is 500,000,000 people. Predict the population for the year 2000 using the logistic growth model on the basis of the data in the years 1940 and 1950. In other words:

* Let P = P (t) be the population, where t is the number of years after 1940.
* Assume P (t) is of the form given by the logistic equation. Determine what the value of L must be in this case.
* Find the exact values of P (0) and P (10) from the U.S. Population table given above. Use these two data points to find the values of b and k in the formula for P (t).
Answer to the nearest 1 million people

Your post needs to include what you are using for the general form of a logistic equation.

Specifically, we need to know what L, b, and k are....
