Table $1.3$
Production Possibilities for Brushes and Combs On the basis of your calculations in Table 1.3, in the production range of 1 to 2 combs the opportunity cost of producing 1 more comb in terms of brushes is
A) 4.
B) 1/2.
C) 2/17.
D) 1/7.

Question

Quizplus · Accepted Answer

The opportunity cost of producing 1 more comb when moving from 2 to 1 comb is calculated by the change in the number of brushes divided by the change in the number of combs. From combination L to M, the number of brushes increases from 17 to 21, which is a change of 4 brushes, while the number of combs decreases by 1. Therefore, the opportunity cost is 4 brushes per comb.
