Answer:
Step-by-step explanation:
[tex]3.5 + 4t \leq 39.5[/tex]
First, let's get anything with a [tex]t[/tex] to one side by itself, so this means we need to subtract [tex]3.5[/tex] from both sides:
[tex]4t \leq 36[/tex]
Finally, let's divide [tex]4[/tex] from both sides to get [tex]t[/tex] by itself on one side:
[tex]t \leq 9[/tex]
