Question

the tape diagram below shows the number of freshman and sophomore students enrolled in math club how many sophomores are enrolled in math club?A.) 28B.) 39C.) 45

Answer 1

Let each box having a question mark be x. The sum of the boxes at the top and bottom would be equal to the total number of freshmen and sophomores. Thus, we have

x + 2x + 6 = 39

3x + 6 = 39

3x = 39 - 6 = 33

x = 33/3

x = 11

Thus, the number of sophomores would be

11 + 11 + 6

= 28

The correct option is A
