Finding Functions in Real Life The Gwinnett County Fair charges $4.00 per vehicle and $1.50 for each person in the vehicle. If you represent the total charge as C as a function of the number of persons (p), what would it look like as a function and as a table? Function Form TABLE FORM P C 1 5.50 2 7.00 3 8.50 4 10.00 People charge + vehicle charge = cost $1.50 per person + $4.00 = total cost Let p = number of people c = total cost 1.50p + 4 = C
