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.
