Describe a simple process for using rates and unit prices that might help someone who is having difficulty understanding these concepts. Include either an example from the text or one of your own to explain the solution process.

my answer is : you could use the price of one bottle of soda from a machine and compare it with a six-pack of the same size of bottles of soda. Which is the better buy?

1.25 divided by 3.99

You have an excellent answer for the first question.

Your answer to the second problem -- 1.25 divided by 3.99 -- should be between 0.25 and 0.35.

i do not know if i have to divide it i was just showing my work

Are you saying that the price of one soda from a machine is $1.25 and the price of a six-pack is $3.99?

Divide $3.99 by 6 to find the price of one cola in the six pack.

i think so i just have to show how i came up with my example for the first price? does that make sense

I just want to make sure I understood the question right?

Yes, I think you understood the problem correctly.

From a machine a cola costs $1.25. In a six-pack a cola costs $0.67. Buying a six-pack saves you $0.58 for each cola.

thanks ms sue

You're welcome, Scooby.

To understand rates and unit prices better, let's follow a simple process using the example you provided:

1. Identify the given information: In this case, you have the price of one bottle of soda, which is $1.25, and the price of a six-pack of the same size bottles, which is $3.99.

2. Determine the unit price: To compare the prices, you need to find the unit price, which is the price per unit or item. In this case, we want to compare the cost per bottle, so we divide the total price of the six-pack ($3.99) by the number of bottles in the pack.

Unit price = Total price / Number of units
Unit price = $3.99 / 6

Simplifying the division gives us a unit price of approximately $0.665 per bottle.

3. Compare the unit prices: Now that we have the unit price for each option, we can compare them to determine which one is the better buy.

The unit price of one bottle from the machine is $1.25.
The unit price of the six-pack is $0.665 per bottle.

Comparing the two, we see that the six-pack has a lower unit price per bottle, making it the better buy.

4. Understand the result: By dividing the total price by the number of items, we can compare the unit prices to determine the better value. In this case, buying the six-pack would save you money compared to buying individual bottles from the machine.

By following this simple process, you can utilize rates and unit prices to make informed decisions about the better value or price for different products.
