in
each subsequent hour, the amount of medicine in her body is 91% of the amount from the
previous hour.
what is the explicit rule for the amount of medicine remaining in her body in the nth hour and
approximately how much medicine would remain in the 8th hour?
round to two decimal places.
use explicit rule for a geometric sequence:
hint: round to two decimals places
