Brooklynn, Jasmine, and Maddie arrive to class early. To pass the time, Jasmine announces that she is thinking of a three digit number. She then tells Brooklynn and Maddie that the number she is thinking of is one of the following: 515 516
519
617
618
714
716
814
815
817
Next, Jasmine whispers the leftmost digit to Brooklynn and then whispers the remaining two digits to Maddie. The following conversation then takes place:
Brooklynn: I don't know what the number is, but I know that Maddie doesn't know too.
Maddie: At first I didn't know what the number was, but now I know.
Brooklynn: Ah, then I know the number too.
From that information, determine Jasmine's number.
