One brand of cereal sells for $3.15 for 10 ounces. What is the unit
price per pound?
a. $.31
b. $5.04
c. $ 3.49
d. $50.40
To find the unit price per pound, we need to convert the price from per ounce to per pound. Since there are 16 ounces in a pound, we can divide the price by 10 and then multiply by 16:
$3.15 / 10 oz * 16 oz/pound = $5.04/pound
Therefore, the correct answer is option b) $5.04.
