Answer:

Step-by-step explanation:

The middle value should be 4%.
The reason why is because if the value inside the parentheses was 1.00, it would be constant. 1.04 is equivalent to a positive change of 4%.
Also, it changes every 1 hour, instead of every 15 minutes, because the function is solving for variable t, which, in this context, represents the time in hours.
