Answer:
see below
Step-by-step explanation:
You might do well to refer to the proof referenced here--the previous slide. We assume it more or less matches what we've done in the attachment.
A palindrome is something that reads the same forwards and backwards.
If the number is a palindrome and it's between 300 and 400, then the
last digit must also be a ' 3 '.
So all we have left to fill in is the digit in the middle.
There are 10 possibilities for that one ... the digits ' 0 ' through ' 9 '.
So there are <em>10</em> palindromic numbers between 300 and 400.
