Question 4583
I'm not sure your 5 steps are the same as my 5 steps, but here are my 5 steps.


Step 1: Identify the variables (Let x = ____ ) 
Let x = number of hours worked
.15 x = union charge for each hour worked.


Step 2:  Write the equation (total union charges).
.15x + $4 =  $29.20


Step 3:  Solve the equation.
Subtract 4 from each side:
.15x + 4 - 4 = 29.20 - 4
.15x = 25.20


Divide both sides by .15:
{{{.15x/.15 = 25.20/.15}}}
x = 168 hours


Step 4:  Answer the question.  
The number of hours worked was 168


Step 5:  Check.

Union dues = $4 + .15*168 
= $4 + $25.20 = $29.20
