Question 30 (10 points) There are two gas stations next to each other at the freeway off-ramp. The ARCO station has low prices but a line of cars stretches out to the street. The Chevron station has no line but charges thirty cents more per gallon. Alice and Bob pull off the freeway one after the other. They both need gas. Bob goes to the end of the line at the ARCO station. Alice pulls to the pump at Chevron. a) Use the concept of opportunity cost to explain, in general, how a rational driver should choose one of these stations over the other. Do not refer specifically to Alice or Bob when answering this part of the question. b) Apply your answer to part (a) of this question to Alice and Bob, assuming that both of them are rational drivers. Give two different reasons whey they behave differently
