the amount of time they have is not changed, however the amount of bands they can fit into that time slot is undetermined and relies on the time they have

Answer:

the first option

Step-by-step explanation:

independent is something you can change OR determine

dependent is something that will happen BECAUSE of the independent and you can not change it

in this case- the sentence states that " the amount of time that the venue has been reserved for DETERMINES how many bands will play"

You can change or schedule how long you want to reserve the venue but how many bands that will play depends on the independent variable (t)

Thats why it say determines, because (t) determines or changes (b)
