I don’t understand this plz help

Is it the wording that's confusing you?

Tolerance is how far away from the desired measurement is acceptable.

You're being asked to find an equation that will be true precisely for all of the acceptable measurements.

For Part A , the option |x-691.15| = 3.15 is correct as this equation can be used to find the maximum and minimum values of x (circumference of the disc).
Part B is super simple , just find the maximum and minimum values of x (circumference of the disc) , max is when the manufacturing tolrence is +3.15mm and min when the manufacturing tolerance is -3.15mm.

How is part a that option? If you do x + 688 as well it = 3.15
