| 3x + 1 | =22

x =7                                    x = -7  2/3

Step-by-step explanation:

| 3x + 1 | =22

Absolute value equations have 2 solutions, one positive and one negative

3x+1 = 22                   3x+1 = -22

Subtract 1 from each side

3x+1-1 =22-1               3x+1-1 = -22-1

3x= 21                         3x = -23

Divide each side by 3

3x/3 = 21/3                      3x/3 = -23/3

x =7                                    x = -7  2/3

to determine the unit cost your would divide the total cost by the number sold.
