Propane costs $3.50 per hundred pounds,
 and there is a $6 monthly delivery fee.  
A family has budgeted $85 for their propane this month.
 Let  'x' hundreds of pounds can the family use without going over budget
Here family has budgeted $85 for their propane.
So the cost for Propane  = $ 3.5x
One month delivery fee $6
Therefore cost + delivery charge not exceed $85
 So 3.5x + 6 ≤ 85
3.5x=85-6 =79 
x = 22.57
Therefore 22 hundreds of pounds can the family use without going over budget
