2 liter for $1.40 a liter hope that helps :)

Answer 2

Answer:  The first option has a higher cost per liter and the required cost is $1.40 per liter.

Step-by-step explanation:  Given that a 2 liter bottle of juice cost $2.80. A box containing six 12 liter bottle sells for $3.90.

We are to select the option that has a higher cost per liter.

We will be using the UNITARY method to solve the given problem.

Option (1) :  

The cost of 2 liter bottle of juice = $2.80.

So, the cost of 1 liter bottle of juice will be

$\ \dfrac{2.80}{2}=\ 1.40.$

Option (2) :  

The cost of six 12 liters bottle of juice = $3.90.

So, the cost of 1 liter bottle of juice will be

$\ \dfrac{3.90}{6\times12}=\ 0.05.$

Since 0.05>1.40, so the option of 2 liter bottle costing $2.80 has a higher cost per liter.

And, the required cost is $1.40 per liter.
