Although Figure 2 shows a family of total costs curves, Figure 1 displays a single unit cost curve because the unit cost curve depends on only one variable, pieces per capita.
Figure 1 shows single unit cost curve while Figure 2 shows a variety of total costs curves.
mnli hypothesis: Figure 1 shows single unit cost curve while Figure 2 shows a variety of total costs curves. premise: Although Figure 2 shows a family of total costs curves, Figure 1 displays a single unit cost curve because the unit cost curve depends on only one variable, pieces per capita.
