To determine which ice cream is more expensive per liter, we need to calculate the cost per liter for each option.
For the 3 liters of ice cream priced at $10, we divide the total cost by the number of liters:
Cost per liter = $10 / 3 liters = $3.33 per liter
For the 4 liters of ice cream priced at $12, we divide the total cost by the number of liters:
Cost per liter = $12 / 4 liters = $3 per liter
Comparing the two calculations, we can see that the 3 liters of ice cream for $10 has a higher cost per liter ($3.33 per liter) compared to the 4 liters of ice cream for $12 ($3 per liter). Therefore, the 3 liters of ice cream are more expensive per liter.
