Best buys

 In this lesson we're going to learn about best buys. Best buys is when the same items have different price, you have no idea which one is cheap or best value for your money.

  Let me tell you that it's not always a largest product or smallest or medium sized item. It matters on each price of each item. To find the price of each amount, you have to divide the total amount to the number of items.

 For example "5 for 45c, 4 for $1, 3 for 99c. Find the best buy."
To find the best buy, 5 for 45c
= 45/5 = 1 for 9c

4 for $1
= 100/4
= 25
=1 for 25c

3 for 99c
= 99/3
=33
= 1 for 33c.

Therefore the answer is 5 for 45c.
