Question

The stadium usher had 100 seats in his section, he roped off nine seats for other stadium workers and then divided the rest equally for seven student groups. How many more seats does each student group receive?

Answer 1

Explanation:

100 - 9 = 91 seats for seven student groups

91 / 7 = 13 seats in each student group

each student group receives 13 - 9 = 4 more seats than the roped off section
