20 square feet of space for each person in a classroom. A classroom 28 feet long and 18 feet wide in an inequality

Question

20 feet/ 28 feet long / 18 feet wide 

Answer 1

What is the maximum number of people who can fit in this classroom?

 

The classroom has an area of 28 * 18 = 504 (area = length x width)

 

Let x = the number of people in the class

 

Each person occupies 20 ft² of space

 

So we have

 

20x ≤ 504

 

x ≤ 504/20

 

x ≤ 25.2

 

What this means is that the maximum number of people who can occupy this classroom at once is 25
