Answers:
Upper Limit = 2.55 cc
Lower Limit = 2.25 cc
cc stands for "cubic centimeters".
==========================================
Explanation:
The tolerance tells us how much we can go over or under our target. It's our margin of error. We add and subtract the tolerance (0.15) from the target we're trying to aim for (2.4)
So the lowest dosage allowed is 2.4-0.15 = 2.25 cc
The highest dosage allowed is 2.4+0.15 = 2.55 cc
The upper limit is 2.55 cc while the lower limit is 2.25 cc
On a number line, we would find that 2.4 is at the midpoint of 2.25 and 2.55; so its at the center of those lower and upper bounds. The distance from the center to each endpoint is the same. That distance would be the tolerance 0.15
