Machu Picchu, an ancient Inca settlement, is located in the Andes Mountains of Peru. Because of low amounts of rainfall, the Inca needed to determine if the mountain spring would provide enough water for the settlement.

The set of ordered pairs below defines the relation between the day of the year on the Inca calendar (x) and the water level at the time (y).

{(1, 10), (151, 15), (203, 20), (357, 8), (612, 13)}

What is the value of the greatest element in the range?
