To find the marginal utility of the second can of Coke, we need to subtract the total utility of the first can from the total utility of the second can:

Marginal utility = total utility of second can - total utility of first can 
Marginal utility = 23 - 15 
Marginal utility = 8

Therefore, the marginal utility of the second can of Coke is 8 units.

Since we are not given any information about the price or cost of the cans of Coke, we cannot determine the best choice.

The First Can of Coke Gives 15 Units of Utility
