3. Kerry writes a list of all the integers from 1 to $n$ on a whiteboard. She uses the digit 0 five times and the digit 9 six times. What is the value of $n$ ?
A 39
B 49
C 59
D 69
E 99
3. C Kerry uses the digit 0 five times and hence the value of $n$ is smaller than 60 . She uses the digit 9 six times and hence the value of $n$ is at least 59. Therefore the value of $n$ is 59 .
