Janet conducts an experiment to measure how much salt she can dissolve in a given amount of water at different temperatures. The following graph shows her results: What is the relationship between the amount of salt dissolved and the temperature of the water in this experiment?

Anew obstacle course is home to several new types of challenging obstacles. one such obstacle is traversing a 15-stair staircase. to make it more challenging, the stairs are not uniformly spaced. rather, the vertical space between consecutive stairs for the first 10 stairs is 113 feet and the vertical space for the last 5 stairs is 134 feet. what is the total vertical distance traveled ascending and descending the entire 15-stair staircase?
