In "The Martian," Mark unfortunately misses the return flight to Earth with the other 5 astronauts and is left alone on Mars. Mark must find a way to survive until rescue arrives. The habitation module has 5 days' worth of food for each astronaut and 50 kilograms of non-drinkable water. There is also a sufficiently large garden that Mark plans to use for growing potatoes. After 30 days, each square meter can yield 2.5 kilograms of potatoes but requires 4 kilograms of water for irrigation. Mark needs to eat 1.875 kilograms of potatoes each day to survive. How many days can Mark survive on the available food and potatoes?
