    (a) Let C = cost Let x = number of miles C = 0.25x + 25 (b) C = 100 Graph C = 0.25x + 25 and C = 100 on the same x-y plane, and read off the x coordinate of the point of intersection (c) Create table C = 0.25x + 25 Plug in your guesses for x into above equation and solve for C. The values for x = 1, x = 10 and x = 100 are already in the table below. x | C ------------ 1 | 25.25 10 | 27.50 100 | 50.00 Continue the table with more values until you get C = 100
