The total time the band needs to reserve studio time is equal to the setup time plus the recording time.
Given that the setup time is 15 minutes and the band needs at least 75 minutes to make the recordings, we can write the following inequality:
t ≥ 15 + 75
Simplifying it further:
t ≥ 90
Therefore, the band must reserve at least 90 minutes of studio time to make the recordings.
