The equation, y = 76 (1.013) x, represents the the population of the United States, after 1900, in millions. The population in 1900 (x = 0) was ... ?

A. 1.0123 million

B. 76 million

C. 76.988 million

D. 77 million

I assume that the equation is supposedly written as, y = (76) (1.013^x). This means that the population of the United States increases by 1.3% every year. If we substitute 0 to the value of x,

y = 76 (1.013^0) = 76 (1) = 76

I assume that the unit for y in the equation is million. Therefore, the answer is letter B. 76 million.
