Several students performed an experiment by dropping marbles of uniform size into a jar of water. They measured the height of the water after every five marbles. The results are listed in the table below. Which function best represents the problem situation and the approximate number of marbles it will take for the water to reach a height of 2 feet?

• f(x) = x + 8; approximately 16 marbles 

• f(x) = 0.3x + 8; approximately 53 marbles 

• f(x) = 0.3x + 6.5; approximately 58 marbles

• f(x) = x + 3; approximately 21 marbles
