Elementary school? I'm a senior in high school, and I'm confused about this question...

This is the thing I'm not getting. If he eats 17/66 of the bag from what was left in the first day, and he eats double that the next, he should be able to finish the bag within 5 days.

Or is it that he eats 17/66 of what was left left from the first day... and then eats 34/66 of what was left on the second day... and eats 68/66 of what was left on the third day... that still doesn't work.

It would take him way less than 27 days to finish the bag of cookies.

Is it just me or is does this question have no answer?

Is the answer 18 days? (Just a random guess)
