The 2000 census found a U.S. population of about 281 million. Write an equation for the U.S. population that assumes exponential growth at 0.7% per year. Use the equation to predict the U.S. population in 2100.
equation: y = P*(1+r)x
P is the initial value (value of y when x = 0), r is the percent change (written as a decimal), and x is the input variable and y is the output variable

Question

The 2000 census found a U.S. population of about 281 million. Write an equation for the U.S. population that assumes exponential growth at 0.7% per year. Use the equation to predict the U.S. population in 2100.  
equation: y = P*(1+r)x   
P is the initial value (value of y when x = 0), r is the percent change (written as a decimal), and x is the input variable and y is the output variable
