An elementary school is taking a busload of children to a science fair. It costs $150.00 to drive the bus to the fair and back, and the school pays each student's $3.00 admission fee. (a) Use a formula to express the total cost C, in dollars, of the science fair trip as a linear function of the number n of children who make the trip. C = 3n+150 (b) Identify the slope and initial value of C. slope initial value Explain in practical terms what these values mean. The slope indicates that for each additional child we take on the trip the total cost increases by . The initial value is , and it is the cost of taking the bus itself to the fair. (c) Explain in practical terms what C(7) means. C(7) represents the ---Select--- initial value total cost (in dollars) of the science fair trip if 7 children make the trip. Calculate C(7). $ I need (d) and rest of problem answered (d) Solve the equation C(n) = 168 for n. n = Explain what the answer you get represents. The solution of the equation 3n + 150 = 168 is the number of students we can take if there is $ to spend.
