How to determine unit cost?












0














I'm currently trying to study the formula for each of these questions.



This is the only page where you see in the picture in which I can't figure out how to calculate the numbers in order to get the answer.



Our books speaks about the formulas but I've tried every possible solution.



There is 3 other pages which I was able to solve just fine but I feel as if I missed an important step into figuring this out.



Here is an image of the questions:

    Your have to express the answer in the units they give you, they’re there in the far right. 600ml costing 2.4 is 0.6L, so cost per unit is 2.4/0.6L=7, for example

    Which one you don't know? In any event Unit cost = Cost / No of Unit e.g. a) water, you have $3.80 / 2L = 1.70 $/L. In some case, you may need to convert the unit in final answer. e.g. b) pure vanilla extract $4.20 / 600 mL = $4.20 / 0.6L = 7.00 $/L.

  • Everything after a and b weren't adding up correctly. I would take the AP Cost and divide it by No. of Units

  • An Example for c) and d), and then 1 Extension Price would be nice.

  • onion : $5.12 / 34 lbs = $5.12 / (34 * 16 oz) = 0.009411 $/oz black pepper : $30.57 / 3 kg = 30.57 / ( 3 * 2.20462 lbs) = 4.62211 $/lbs So after round to 3 decimal place, the number for (c) is correct, the one for (d) looks like a typo. For the extension price, let's take salt as example, you want 1/4 tsp * 1.54 $/fl oz = 1/4 x 1/6 fl.oz * 1.54 fl.oz = (1.54)/(4*6) $ = 0.0641666 $ rounding down to 3 decimal places, the supplied answer also looks correct. At the end, what you really need is a converter between different unit and I use google to do the conversion.
