First, find all the values on the line plot.
5 1/4, 5 1/4, 5 1/4, 5 1/2, 5 1/2, 6 1/4, 6 1/4, 6 1/4, 6 1/4, 6 1/4, 7 1/4, 7 1/4, 7 1/2, 7 3/4
Second, add all the numbers.
5 1/4 + 5 1/4 + 5 1/4 + 5 1/2 + 5 1/2 + 6 1/4 + 6 1/4 + 6 1/4 + 6 1/4 + 6 1/4 + 7 1/4 + 7 1/4 + 7 1/2 + 7 3/4 = 87 3/4
Therefore, the answer is A.
Best of Luck!
