8. A landscaping company is hired to mow the grass for several large properties. The total area of the properties combined is 820 acres. In one hour one person can mow 2.8 acres, so the regression equation is as follows: --2.8X + 820 Where X is the number of hours worked and represents the number of acres left to mow. a. How many acres will be left to mow after 40 hours of work by one person? b. How many acres will be left to mow after 100 hours of work by one person? (now you see why you need a large crew to mow many acres!) 8. A landscaping company is hired to mow the grass for several large properties. The total area of the properties combined is 820 acres.
