An audiologist is
testing a patient to determine the softest sound of a specific frequency that
the patient reports hearing. She begins with a 10(dB) sound for trial 1, then
increases the volume by 2dB for each trial after that. If the patient can hear
all sounds of that frequency that have a volume louder than 26, and t
represents the trial numbers that the patient can hear, which of the following
inequalities best models the situation described above?
a. 2t+6≥10
