start by remembering that the drive time is the x on the equation and the score will be the y on the equation.

[tex]\begin{gathered} y=1.365x+39.431 \\ \text{replace 50 on the x} \\ y=1.365(50)+39.431 \\ y=107.681 \end{gathered}[/tex]

the test score will be about 107.681%

The answer above does not seem reasonable because the maximum score you can obtain is 100%, this is because the correlation coefficient is 0.767 which means that the data is not model correctly, it should be model with a different type of equation so that the answer is more precise.
