Best buys problems involve assessing which item is the best value for money.this involves calculating the price per unit for each item.
We find the unit price of each item, then comparing the unit prices, we decide that the item with the smaller unit price is the "best buy".
We learn that the unit price is the cost per unit, and to find the unit price, divide the price by the number of units.
You want to find the base unit, which is price per oz.
For the brand A
$9.60/15 oz= .064 or 6 cents per oz
For the brand B
$13.00/ 20 oz= .65 or 7 cents per oz
