Identify Given Equation: Let's identify the given equation that represents Roger's elevation over time. The equation provided is $y = 30x + 20$ , where $y$ is the elevation in feet and $x$ is the time in minutes.
Predict Elevation After $10$ Minutes: Now we need to use the equation to predict Roger's elevation after $10$ minutes. To do this, we will substitute $x$ with $10$ in the equation $y = 30x + 20$ .
Perform Substitution and Calculation: Perform the substitution and calculate the value of $y$ when $x$ is $10$ . $y = 30(10) + 20$
Calculate Final Elevation: Now, let's do the multiplication and addition to find the value of $y$ . $y = 300 + 20$
Calculate Final Elevation: Now, let's do the multiplication and addition to find the value of $y$ . $y = 300 + 20$ Add $300$ and $20$ to get the final elevation. $y = 320$
