Table 2.4 shows that the first tank of fertilizer increased the yield from 30 to 50, the second tank increased it from 50 to 70, but the third tank only increased it from 70 to 80. This is an example of the principle of diminishing returns, where the marginal increase in output decreases with each additional unit of input. Therefore, the best choice would be the addition of the third tank of fertilizer, after which the additional yield is not significant enough to justify the cost of adding more fertilizer.
