In an article in the April 2012 issue of the Newton Conservators newsletter you can read that In the early 1970s there were approximately 40,000 trees lining the streets of Newton. Today, that number is about 26,000-a 35% loss. The current annual rate of decline is about 650 trees per year. At this rate, if unchecked, public street trees would diminish to approximately 10,000 within a generation (25 years), and in 40 years, public street trees would no longer be part of the Newton landscape. a. Check the arithmetic that leads to the claimed "35% loss". the b. Check the arithmetic that leads to a "current annual rate of 650 trees per year". c. Check the predictions in the last sentence. Are they likely to come to pass? d. Write the equation for the linear model implicit in this quotation (use years since 2012 as the independent variable). Identify the slope and the intercept, with their units.
