Philip answered him, “Eight months’ wages would not buy enough bread for each one to have a bite!”
It was actually more than 200 dinarii in the Greek. The dinarius was a day's wage for a working man.
What I want to emphasize is how over the top is the amount. These miracles in John's gospel were not hole in the corner affairs. The water turned into wine in was six 20-30 gallon jars. The woman at the well had had 5 husbands, not just a couple, the man had been waiting for 38 years for the water to stir and now here it would have required more than eight month's wages even to give every one a bite!. Jesus was being extravagant in his miracle working. He will still walk on water and raise the dead.
No wonder there were crowds.
