Answer:
No, since the marginal cost of consuming the ice cream cone is greater than the marginal benefit.
Explanation:
Marginal utility is the benefit that a consumer derives from consuming an extra unit of a product. To maximise satisfaction consumers tend to go for products that will give them high satisfaction at a low cost.
In the given scenario the cost of a unit of ice cream cone is $3.05, and the satisfaction or benefit is $3. The cost is higher than satisfaction gained. A consumer will not buy the ice cream under these conditions. They will rather look for an alternative that will give high satisfaction at low cost.
