Answer:
20 cents
Explanation:
The marginal cost refers to the cost of an extra unit. In this case, if she decides to purchase two tacos and a medium drink, she would spend $2.30. The difference between this option and the value meal, that contains three tacos and a medium drink, is 20 cents. The marginal cost of purchasing the third taco if she takes the second option would be 20 cents. If she decides to buy the tacos and the drink for apart, the marginal cost or extra unit cost would be 75 cents.
All of the above. Hope this helped

The turnover Pulse hypothesis states that generalist eaters confronted excessive charges of extinction during the ice a long time.
The pulsed climate variability framework indicates there are durations of extreme weather variability every 400 or 800 kyr pushed via the eccentricity maxima while lakes rapidly develop and fill tons of the Rift Valley and then unexpectedly disappear.
Phylogenetic turnover quantifies the evolutionary distance among species assemblages and is principal to expertise the main drivers shaping biodiversity. its miles affected each by means of the geographic and environmental distance between websites.
