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.
