April can buy a package of 10 folders for $1.20 or a package of 8 folders for $1.12. Which is the better buy?

Question

I need to find the better buy of the 2, 10 for $1.20 or 8 for $1.12.

Answer 1

Yes, you've reached the correct result.

But be sure you know the method:

 

Divide each of the TOTAL costs by the number of folders you would get at that price.

So $1.20 / 10

compared with $1.12 / 8.

 

You can practice this when you go to the store shopping--this is a frequent practical use for this kind of question.

Your favorite crackers are on sale at two different store. At one store, they're 5 for $10.00.

At the other store, they're 3 for $8.00.

 

Same concept--divide the total amount you would pay if you spent the WHOLE $10 or $8, by the number you'd get for that amount (5 and 3, respectively).

 

And then you know which one is the better deal!

 

Answer 2

10 for 1.20 is 12 cents a piece

 

8 for 1.12 is 14 cents a piece.

 

It's division.
