Each day he eats either 9 carrots, or 4, or none.

There is only one combination of 9's and 4's that adds up to 30.

Find that combination (I leave that to you) and finish the problem from there.

Here is a hint: the total number of carrots is an even number; 4 is even but 9 is odd. That means the number of days he eats 9 carrots must be even.
