A human factors expert recommends that there be at least 9 square feet of floor space in a college classroom for every student in the class. Find the minimum floor space that 96 students require.

864 sq ft

Step-by-step explanation:

Given that a human factors expert recommends that there be at least 9 square feet of floor space in a college classroom for every student in the class.

The number of students in the class = 96

For 1 student space required = 9 sq ft

For 96 students = ?

This is a question of direct variation since when number of students increase space required also would increase.

Hence we get the minimum floor space that 96 students require.

=96*9

=864 sq ft
