Price per ounce is $0.062
Step-by-step explanation:
Here, we want to find the unit price in which this vase is price per ounce
Firstly, we need the total ounce value
1 pound = 16 ounce
so two pounds will be 2 * 16 = 32 ounces

So 40 ounces = $2.48
price per ounce will be $2.48/40 = $0.062 per ounce
