Answer:
1.4071
Explanation:
The relationship between the elapsed time, t in days, since an ocean sunfish is born, and its mass is given by:

This function represents an exponential growth increasing as the number of days increases since (3.5 > 1), it means that at day 0 , the mass of the sunfish is 3.5 milligrams and every day, its mass increases by a factor of 1.05.
Since the mass of the sunfish increases by
, therefore the mass of the sunfish increases every one week (that is 7 days) by a factor of
