Answer:
a) C(t) = 425(1.048)^t
Explanation:
Formula for an exponential function: a * b^x
a = initial value, b = growth / decay rate
The initial value is 425 mL, so a = 425.
The capacity increase by 4.8% per hour (need to convert to decimal, so b = 1.048)
Therefore, the answer is 425 (1.048)^t, or a
