The graph represents the revenue R (in millions of dollars) for Chipotle Grill from 2007 through 2013, where t represents the year, with t = 7 corresponding to 2007. a. Estimate the slope of the graph for the year 2008. Show all calculations and interpret the result in the context of the problem. (communication/interpret) b. Explain how you may use the graph to estimate the total Revenue from 2007 to 2010. What assumptions are you making, is the estimate an over estimation or under estimation? Explain. calculate the estimate. (Assumptions/Application/Analysis) c. Suppose the Revenue function R is modeled by the equation: .90) = 41.59721:3 4- 51.1137:2 485.54t + 2199.0 Formulate and obtain the total Revenue from 2007 to 2013 using the Revenue function RU).
