Howard · Answer 1

We know that the real number of tickets sold was within 35 tickets of 350.

"no more than 35" implies a difference less than or equal to 35, meaning we want to use ≤ in our equation.

The following absolute value inequality describes our ticket range:

|350 - x| ≤ 35

Plug a few numbers in for x to make sure this function makes sense:

x = 360

|-10| = 10 ≤ 35

x = 300

|50| > 35, does not comply with our inequality.
