Cecil is in jail for five years for killing some hikers. He decides he wants to tunnel out.
He has very little to work with, however. He has a spoon, a fork, and a toothbrush. He also has to worry about disposing of the dirt. First, he has to get the bricks out. It takes about 1 month (30 days)/brick, using the fork. Then he has to dig through 100 feet of earth. If he removes 12 bricks, it take about 18 days to dig through each foot of earth. If he removes 25 bricks, it takes only 14.1 days to dig through a foot. In addition to the digging, he also has to dispose of the dirt. For each foot he digs, he spends 7 days disposing of the dirt.
How many days will it take Cecil to get out of jail?
