Figure 2.1. Production Possibilities Schedule Tons of Aluminum 1000 1000 Tons of Steel Figure 2.1 shows a straight-line production possibilities curve with tons of Aluminum on the vertical axis and tons of Steel on the horizontal axis. The intercept on the vertical axis equals 2000 and on the horizontal axis equals 4000. The production possibilities curve shows a point where the tons of aluminum on the vertical axis 1000 and the tons of steel on the horizontal axis is 2000. Referring to Figure 2.1, the relative cost of steel in terms of aluminum is: 4.0 tons 2.0 tons O 0.5 tons O 0.25 tons
