Quizplus · Accepted Answer

Working backward is the most efficient method for this problem because we are given the final change amount and need to determine the initial amount given to the cashier. We can work backwards to subtract the cost of the items from the initial amount and see if it matches the change given. The other methods listed, such as forming subgoals, trial and error, and using an analogy, are not applicable or efficient for this specific problem.
