The Yert family hires a landscaping company for 30 weeks. There are two companies to choose from. Green Lawns charges $2 for the first time they service your lawn, and the price will multiply by a factor of 1.00 every week thereafter. Green Thumbs charges $200 for the first time they service your lawn, and then charges an additional $50 every week thereafter. At 30 weeks, if the Yert family chooses the company that is cheaper, how much money will they save?
