Regina is comparing the cost to rent a car from four different companies. She found that the cost to rent from each company can be modeled by a linear function of the number of miles driven. The formulas for each company are shown in the table. Daily Cost to Rent a Car Driven x Miles Company Cost in dollars 1 y = 18 + 0.05 x 2 y = 0.27 x 3 y = 27 4 y = 18 + 0.06 x Which statement is best supported by the table? Company 1 and company 4 charge the same rate per mile. Company 2 and company 3 charge the same rate per mile. Company 2 charges only a flat fee and does not charge per mile. Company 3 charges only a flat fee and does not charge per mile.
