What is the better buy? Defend your answer by writing a statement that compares the two quantities. Better buy means CHEAPER per unit price.

3 batteries for $4.80 or 12 batteries for $14.76?

Option B is the cheaper deal (the 12 batteries for $14.76)

Explanation:

For the first deal we can say

3 batteries = 4.80 dollars

3/3 batteries = 4.80/3 dollars divide both sides by 3

1 battery = 1.60 dollars

The unit price for the first deal is $1.60 per battery.

For the second deal we could say

12 batteries = 14.76 dollars

12/12 batteries = 14.76/12 dollars divide both sides by 12

1 battery = 1.23 dollars

The unit price for the first deal is $1.23 per battery.

This is the cheaper deal.

So in short, you're dividing the total cost over the number of items to get the unit price.
