To find the unit price per pound of the salad greens, we need to convert the weight of the salad greens from ounces to pounds.
Since there are 16 ounces in a pound, we can divide the weight in ounces (5 ounces) by 16 to get the weight in pounds.
5 ounces / 16 = 0.3125 pounds
Now, we can find the unit price per pound by dividing the total cost ($4.00) by the weight in pounds (0.3125 pounds).
$4.00 / 0.3125 pounds = $12.80
Therefore, the unit price per pound of the salad greens is $12.80.
Thus, the correct answer is C. $12.80
