The ideal is 28.75 inches, so one would hope that all of the basketballs would be exactly 28.75 inches in circumference. But perfection is not possible, so we have to allow for some variability. The standard states the circumference can vary by "at most 0.25 in."
.
That means a basketball that is 28.75+0.25 in circumference is acceptable.
That also means a basketball that is 28.75-0.25 in circumference is acceptable.
This idea of + or - some amount is shown as:

.
Solve each part:
The smallest acceptable circumference will be:

.
The largest acceptable circumference will be:

.
So the circumference can vary from 28.5 to 29 in.
