To solve this question you need to replace t in the equation for the values asked.
For 0:
[tex]\begin{gathered} d=25(0) \\ d=0 \end{gathered}[/tex]For 1:
[tex]\begin{gathered} d=25(1) \\ d=25 \end{gathered}[/tex]For 2:
[tex]\begin{gathered} d=25(2) \\ d=50 \end{gathered}[/tex]For 3:
[tex]\begin{gathered} d=25(3) \\ d=75 \end{gathered}[/tex]It means the values for 0, 1, 2 and 3 are 0, 25, 50 and 75 respectively.
