Question

A company did a quality check on all the packs of roasted almonds it manufactured. Each pack of roasted almonds is targeted to weigh 21.25 oz. A pack must weigh within 0.24 oz of the target weight to be accepted. What is the range of rejected masses, x, for the manufactured roasted almonds?

x < 21.01 or x > 21.49 because |x - 0.24| + 21.25 > 0
x < 21.25 or x > 21.49 because |x - 21.25| > 0.24
x < 21.01 or x > 21.49 because |x - 21.25| > 0.24
x < 21.25 or x > 21.49 because |x - 0.24| + 21.25 > 0

Answer 2

Draw a number line and make sure 21.25 is labeled on it

Answer 3

the accepted range is within 0.24 oz

so add 0.24 to 21.25 to get 21.49

Answer 4

subtract 0.24 from 21.25 to get 21.01
