Question

Can someone please the graph the following solution?

18 ≤ x ≤ 22

The problem was:
A candy company places an average of 20 truffles in a one-pound box. The number of truffles
per box never varies from the average by more than 2.

a. Write an absolute value inequality to represent this situation, using x to represent the actual number of truffles per box.
| x - 20 | ≤ 2

b. Solve the inequality. Show all work leading to your answer.
-2≤x-20 ≤ 2

-2+20 ≤x-20+20 ≤ 2+20

18 ≤ x ≤ 22
c. Graph the solution on the number line. Be sure to include number labels to show the values of x on the number line.

Answer 1

we have that

`18 \leq x \leq 22`

using a graph tool

see the attached figure

the solution is the interval [18,22]
