You answer it with simple math
Adelle took 84+12, or 96 pictures in all, including the unspoiled ones too. And since there are 24 pictures in each roll, you divide 96 by 24.
96/24 gives you 4.
So Adelle used 4 rolls of film.
Hope this helps.

Answer:
5.73 hours
Step-by-step explanation:
70% decay means 30% remains
.3 = (1/2)^(t/3.3)
take the log of both sides
log.3 = t/3.3 * log1/2
Divide both sides by log 1/2
log.3 / log1/2 = t/3.3
use calculator
1.736965594166206 = t/3.3
multiply both sides by 3.3
5.73198646074848 = t
rounded
t = 5.73 hours
