Quizplus · Accepted Answer

The opportunity cost for combs in terms of brushes is calculated by the difference in the number of brushes produced as we move from one combination to the next, divided by the change in the number of combs. From J to K, the opportunity cost is (10-0)/(4-3) = 10 brushes per comb. From K to L, it's (17-10)/(3-2) = 7 brushes per comb. From L to M, it's (21-17)/(2-1) = 4 brushes per comb. The lowest of these calculated opportunity costs is 4 brushes per comb, which corresponds to moving from L to M. However, the correct calculation method and the options provided suggest a misunderstanding in the explanation process, as none of the calculated values directly match the options given. The correct approach to find the lowest opportunity cost should compare the incremental changes correctly, but without the specific calculations for each option provided in the question, the explanation above misinterprets the available options. The correct answer, based on the options given, should reflect the lowest opportunity cost between the provided combinations, which would typically be calculated as described but seems to have been misunderstood in this explanation.
