1. Given that Naoko used 450 minutes and was charged ¥13,125, it follows that F + (450 − 420)M = 13,755, or F + 30M = 13,755. However, the value of F cannot be determined. For example, F = 13,005 and M = 25 is possible, and F = 13,035 and M = 24 is possible; NOT sufficient.
2. Given that Naoko used 400 minutes and was charged ¥13,125, it follows that F = 13,125, since Naoko did not use more than 420 minutes; SUFFICIENT.
The correct answer is B;
statement 2 alone is sufficient.
