Fertilizer Application Decision
A farmer is deciding how many bags of fertilizer to apply to a field. The table below shows the total crop yield (in bushels) for different quantities of fertilizer. The price of one bushel of crop is $10, and the cost of one bag of fertilizer is $45.
| Bags of Fertilizer | Total Yield (bushels) |
|---|---|
| 0 | 100 |
| 1 | 110 |
| 2 | 118 |
| 3 | 124 |
| 4 | 128 |
| 5 | 130 |
Based on an analysis of the incremental change, should the farmer apply the 4th bag of fertilizer? Calculate the relevant values and explain your reasoning.

A coffee shop is considering staying open for an additional hour, from 4 PM to 5 PM. The table below shows their total revenue and total costs for different hours of operation. Based on an analysis of the change from the 4th to the 5th hour, what is the most logical decision and why?

Decision on Studying
A software company has invested $5 million in developing a new product. Due to unexpected competition, the projected future revenue from the product has dropped to $3 million. The company estimates it will cost an additional $1 million to complete the product. Based on a rational analysis of incremental changes, the company should abandon the project because the total cost ($6 million) will exceed the total revenue ($3 million).
Marginal vs. Average Analysis in Decision-Making
A rational decision-maker thinks at the margin by comparing the additional benefits and additional costs of a small change. For each scenario below, match it with the correct marginal comparison that should guide the decision.
Rational individuals make decisions at the margin. This means they will choose to take an action only if the additional, or marginal, benefit of the action is at least as great as the marginal ____.
A firm is considering whether to produce one additional unit of a good. Arrange the following steps in the logical order a rational decision-maker would follow when thinking at the margin.
