Suppose you are going on a weekend trip to a city that is d miles away. [a] Develop a model that determines your round-trip gasoline costs. Let d = distance, m = miles per gallon, p = price per gallonr and C = total cost. 5. I; [b] What assumptions or approximations are necessary to treat this model as a deterministic model? {Select all that apply.) Z] We use the same route on the outbound and the inbound leg of the trip. Ll p does not vary by location. .FJ m varies depending on city and highway trafc conditions. :l p varies by location and due to local taxes. J m does not vary for the duration of the trip. [c] Are these assumptions or approximations acceptable? O A reasonable person would conclude that the real cost would deviate widely from the estimate and reject the approximation. {3' A reasonable person would assume average values for m and p and accept the approximation. (3' A reasonable person would hedge their bets and increase the budget by 20% over the estimated cost. (3 A reasonable person would note that neither m norp can be known ahead of time and reject the approximation
