<p>A group of biologists is surveying the mice population in a forest. The equation \(n=75\cdot 3^t\) gives the total number of mice, \(n\), \(t\) years since the survey began. Explain what the numbers 75 and 3 mean in this situation.</p>

<p>75 is the initial number of mice in the forest when the survey started, or the number of mice when \(t\) is 0. The 3 is the growth factor or constant ratio, meaning that each year, the population of mice in the forest is 3 times the previous year’s population.</p>
