The price of drink is given as 0.10 dollars per deciliter.
It says to find the cost of 2 liters of drink.
We need to convert the units from liters to deciliters.
We know 1 liter = 10 deciliters.
then 2 liters = 20 deciliters.
So we need to find the cost of 20 deciliters of drink at rate of 0.10 dollars per deciliter.
1 deciliter of drink cost = 0.10 dollars.
20 deciliter of drink would cost = 20 x 0.10 dollars = 2.00 dollars.
Hence, 2 liters of drink would cost 2 dollars.
