Raymond is trying to save up some money to buy a car. He found a great used El Camino that a friend of his dad's is willing to sell him for $3500. Raymond has two jobs,
ne mows lawns and stains/paints fences. Raymond makes $20 for every lawn and $5 for
every 6 foot section of fence. How many lawn and/or fence jobs must he complete to
have at least enough to buy the car?
