One brand of cereal sells for $2.89 for 9 ounces. What is the unit
price per pound?
a. $.32
b. $4.29
c. $2.15
d. $5.14
To find the unit price per pound, we need to convert 9 ounces to pounds and then divide the price by that amount. There are 16 ounces in a pound, so:
9 ounces = 9/16 pounds
Now we can find the unit price per pound:
$2.89 / (9/16) pounds = $2.89 รท 0.5625 pounds
Simplifying this division, we get:
$5.14
Therefore, the answer is d. $5.14.
