Hey there!
In order to solve this question, we want to isolate "t" on one side of the final equation using the original equation of [tex]G=-4t+100[/tex].
Let's start off by adding 4t to both sides of the equation. This will remove the "-4t" on the right side of the equation.
Now we have [tex]G+4t=100[/tex].
Now, let's subtract both sides by G. This will move the "G" on the other side.
[tex]4t=100-G[/tex]
Now, let's fully isolate t by dividing both sides by 4. This will remove the coefficient for t.
[tex]t=\dfrac{100-G}{4}[/tex]
Thus, your answer is C. Hope this helps! :)
