A certain community college charged $57.50 per credit (unit or hour) for tuition in spring semester 2009. Let T be the total cost (in dollars) of tuition for enrolling In c credits of classes. Answer through (a) to (d). a. Complete the table to help nd an equation that describes the relationship between c and T. Show the arithmetic that helps to identify the pattern. "$ng Total Cost T(in dollars) I: 3 [57 50 - + 6 [57 50 - + 9 [57.50 - + 12 [57 50 - + T : (Type an expression using c as he variable.) b. Perform a unit analysis ofthe equation found in part (a). Choose the correct answer below. 0 A. In the equation, the units on one side are dollars and the units on the other side are credits, so the equation is correct. 0 B. In the equation, the units on both sides are credits, so the equation is correct. 0 C. In the equation, the units on both sides are dollars, so the equation is correct. c. Graph the equation by hand. Choose the correct graph below. The cost of a particular private school begins with a onetime initiation fee of $2000 plus annual tUition of $4,000 This srtuation can be modeled by a linear function. identify the independent and dependent variables. Draw a graph of the function, then use the graph to nd the cost to attend this school for 2 years is a linear model reasonable for this situation? The numberofyearsis the independent variable, The cost is the dependent variable, Use the graphing tool to graph the line. The cost for 2 years is $ A linear model V reasonable. The cost of an airline ticket is proportional to the distance traveled at a rate of $14 per 50 miles own Assume that there is a base charge of $75. Complete parts (a) through (c).
