Final answer:
To find the utility-maximizing combination of cheese and fruit, calculate the ratio of marginal utility to price for each and equalize these ratios for the last kilogram consumed of each. This is used in the consumer equilibrium determination.
Step-by-step explanation:
To calculate the marginal utility per dollar from the last kilogram of cheese and the last kilogram of fruit, one must understand the principals of consumer choice and budget constraints. To find the utility-maximizing choice on a consumption budget constraint, we use one of three methods. Firstly, we could sum up the total utility of each choice on the budget line and select the one with the highest total. Secondly, we could start from a random choice and compare the marginal utility gains and losses from moving to neighboring points to eventually find the most preferred choice. Thirdly, and most relevant to this question, we would calculate the ratio of the marginal utility to the price for each good (cheese and fruit) and at the consumer equilibrium, these ratios will be equal.
This means that to maximize utility, the last dollar spent on cheese should give the same satisfaction as the last dollar spent on fruit. Therefore, you would use the provided information to calculate these ratios, insert the results into the corresponding menus in your analysis tool or system to compare them, and adjust your consumption choices accordingly until those ratios match. The proper choice to complete the sentence in the question would be: Use the dropdown menus in the Consumer equilibrium determination.
