A scientist is studying wildlife. She estimates the population of bats in her state to be 270,000. She predicts the population to grow at an average annual rate of 2.9 percent. Using the scientist’s prediction, create an equation that models the population of bats, y, after x years.

• y = 270(1.29)^x

• y = 1.029(270000)^x

• y = 270000(1.029)^x

• y = 270000(1 + 2.9)^x
