Question

A school bus can hold a maximum of 45 students. The correct inequality for this word problem is b ≤ 45. Why did I use ≤ not < in this problem?

Answer 1

This sign ≤ means greater than or equal to

but, this sign < means the number which is in the side is only greater

That why the sign ≤ is used

My this answer might be wrong , because in b ≤ 45 , I am confused from where the letter " b " came from .

Answer 2

because it can still hold 45, if you did the other it meant it couldn’t hold 45
