Answer:
Let's assume that the bill amount without the late fee is represented by "x".
Since Adelaide paid $416.02, which includes a late fee of $3.00 per day for 5 days, we can set up an equation:
x + 5($3.00) = $416.02
Simplifying the equation:
x + $15.00 = $416.02
Subtracting $15.00 from both sides of the equation:
x = $401.02
Therefore, the bill amount without the late fee was $401.02.
