barxatty [35]

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

Step-by-step explanation:

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.

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

Option (2) :  

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

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

The formula A=P(1+r)t is used to show the total amount owed for a loan with a simple annual interest rate.
vodka [1.7K]
We are asked to express r in terms of A, P, and t.

We first divide both sides of the equation by t, which gives us

                                         
                     \displaystyle{ \frac{A}{t}=P(1+r), 


then, dividing both sides by P, we have

                     \displaystyle{ \frac{A}{Pt}=1+r.

Swap the sides:

                    \displaystyle{ 1+r= \frac{A}{Pt} 
      
Finally subtracting 1 from both sides gives us

                     \displaystyle{ r=\frac{A}{Pt}-1.
