A 2 liter drink costs $0.10 per deciliter. How much does the drink cost?

Answer 1

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.

I liter is ten deciliters
0.1*20=2
2 dollars
