Answer:

320

Step-by-step explanation:

To know what were the sales, after 13 years, we need to replace t nu 13 on the original equation, so


\begin{gathered} S(t)=170+50\log_3(2t+1) \\ S(13)=170+50\log_3(2(13)+1) \\ S(13)=170+50\log_3(26+1) \\ S(13)=170+50\log_3(27) \\ S(13)=170+50(3) \\ S(13)=170+150 \\ S(13)=320 \end{gathered}

Therefore, the approximate sales after 13 years were 320 thousand units.
