50 POINTS PLUS BRAINLIEST FOR CORRECT ANSWER!! While conducting an experiment of dropping marbles into a glass partially filled with water, it was observed that the water level rises consistently for each marble added. This experiment is shown below. It should also be noted that further into the experiment it was observed that a total of 7 marbles in the glass resulted in a water level of 7.25 cm. Model this relationship appropriately to determine how many marbles would result in glass being exactly half full. Also, find the maximum number of marbles that can be added before the glass overflows. And make a determination of how much water was in the glass originally.
