Those would be minimum wage jobs that you are referring to right? So work harder and it won't be so hard to afford it. A little obvious math. The tank on my truck holds 22 gallons. Multiply that by the $3.69 I paid last night and you get $81.18. Now divide that by the minimum wage of $5.75. OK. That works out to 14.7 hours just to fill the tank of my truck.
