Question 6

Investment in capital goods is one way to increase the standard of living in the future. Investment in capital goods, however, means that we must forgo consumption today.

With this information we know that the opportunity cost of which of the following is the greatest? $$\begin{array}{l}\begin{array} { | c | c | } \hline\text { Current consumptinn }& \text { Future conguptinn }\\\hline 800 & 100 \\\hline 750 & 260 \\\hline 650 & 340 \\\hline 600 & 380 \\\hline 550 & 400 \\\hline\end{array}\end{array}$$
