Greg needs to hire someone to clear his driveway of snow this winter season. A neighbor has a plow attached to his truck and charges $30 for each time he plow the driveway. Mel's Landscaping runs a snow clearing business and charges $50 for the first time they plow and $25 for each additional time they plow. Write and solve an equation to determine when the costs of each option are the same. Under what conditions would Greg choose his neighbor? Mel's Landscaping?
