To find the initial value, we need to determine the rate at which the fine increases per day. We can do this by calculating the difference in the fine between consecutive days.
The increase in the fine from day 2 to day 3 is 45 cents - 30 cents = 15 cents.
The increase in the fine from day 3 to day 4 is 60 cents - 45 cents = 15 cents.
Since the increase in the fine is constant at 15 cents per day, we can deduce that the initial value is 30 cents - 15 cents = <<30-15=15>>15 cents. Answer: \boxed{15}.
The increase in the fine from day 2 to day 3 is 45 cents - 30 cents = 15 cents.
The increase in the fine from day 3 to day 4 is 60 cents - 45 cents = 15 cents.
Since the increase in the fine is constant at 15 cents per day, we can deduce that the initial value is 30 cents - 15 cents = <<30-15=15>>15 cents. Answer: \boxed{15}.
