Question

Coca-Cola is sold in a variety of different packages. Find the unit cost of each package to find the betterbuy. (Round to three decimal places)a. $4.99 for a case of 24 twelve-oz cansb. $5.00 for a 12-pack of 8-oz cans

Answer 1

Ok, so

We want to find the unit cost of each package to find the better buy.

We know that $4.99 is the cost for a case of 24 twelve-oz cans.

If we divide:

$\frac{4.99}{24}=0,20791$

Then, the cost for each can in the option a, is $0.20791.

Now, we know that $5.00 is the cost for a 12-pack of 8-oz cans.

If we divide:

$\frac{5.00}{12}=0.4166$

Then, the cost for each can in the option b, is $0.4166

Notice that in the option a, we know that there are cans with 12-oz.

The unit price, can be found if we divide the price of each can, by its capacity.

In the option A, we obtain:

$\frac{0.20791}{12oz}=0.017$

This is, 0.017 dollars per oz.

In the option b, we know that there are cans with 8-oz.

If we calculate the unit price, we got that:

$\frac{0.4166}{8oz}=0,052$

This is, 0.052 dollars per oz.

If we compare, we clearly notice that the best option to buy is a, because the units (dollars / oz) indicates us that the price for each oz, is cheaper, with 0.017 dollars / oz.
