When planning a more strenuous hike, Erin figures that she will need at least 0.8 liters of water for each hour on the trail. She also plans to always
have at least 1.50 liters of water as a general reserve. If x represents the
duration of the hike (in hours) and y represents the amount of water needed
(in liters) for a hike, the following inequality describes this relation:
y 20.8x + 1.5
Which of the following would be a solution to this situation?
