To solve the problem, we need to subtract the fixed $5.00 fee from John's total bill of $50.00. This leaves us with $45.00 that was charged based on the number of calling minutes.

To find the number of minutes, we can divide the remaining charge by the cost per minute:

$45.00 ÷ $0.10 per minute = 450 minutes

Therefore, John used 450 minutes of calling time. Answer choice C is correct.
