We have the next information given:
-Karen's fish tank has 18 liters of water in it.
-She plans to add 6 liters per minute until the tank has more than 66 liters.
We can write more than using the next inequality symbol ">".
in this case, we need to use the t variable and it depends on the liters per minute.
Hence, we can write the next expression:
[tex]6t+18>66[/tex]We add 18 liters because the fish tank has already this amount of water in it.
Now, we need to solve for t:
[tex]\begin{gathered} 6t>66-18 \\ 6t>48 \\ t>\frac{48}{6} \\ t>8 \end{gathered}[/tex]Hence, Karen could add water for more than 8 minutes to get more than 66 liters.
The inequality answer is t>8.
