Absolute values and inequalities

Question

The maximum weight of a bag is 16.4 oz and the minimum weight is 15.6oz, write an equation and solve

Answer 1

16 is halfway between 15.6 and 16.4, at a distance of 0.4 from each.

Let x = weight of a bag

Then l x - 16 l ≤ 0.4

So, -0.4 ≤ x - 16 ≤ 0.4

15.6 ≤ x ≤ 16.4

Answer 2

It's unsure what exactly what the question is wanting, but I can take a crack at it. To write this out as an inequality I will use the variable x to represent the weight of the bag. The x will go in the middle of the two limits (minimum and maximum) with the appropriate alligator signs.

15.6 ≤ x ≤ 16.4
