8 ounces = 1 cup 4 ounces = 1/2 cup So yes, 12 ounces is equal to 1 1/2 cups.
Since 1 pound is equal to 16 ounces, you need to divide (181 cups per pound) by 16 to get the total cups per ounce. This equation will tell you that there are 11 cups per ounce of tea. Once you know this, the equation is: (Cost of tea) / (Ounces of tea * 11) = Cost Per Cup.
