I am probably thinking this thru the wrong way, since math is a very weak subject for me. Here is my math problem:

Price matix helps to calculate how many cups of icing you need to ice a given size cake. "X" cups of icing is involved in formula for cost calculations. A container of premade buttercream is 24 lbs (10.88 kg). How many cups of icing are in this container? If the whole 24 lb. container costs $40, how much money is one cup of icing?

I'm thinking I need to know the the weight (mass?) of an 8 oz volume cup of icing. I don't have a kitchen scale and hope someone can tell me about how much a cup of medium consistency buttercream weighs? I don't know the recipe, but it is about the consistency of the high humidity icings with Dream Whip. Stiff enough for borders, would probably need some more PS added to it for roses. I tried guesstimating by the feel of the weight of my hand, I'm clueless.

I'm hoping someone will steer me in the right direction, for I am sure I am way off course. The only other option I can think of is to measure out cup by cup how many cups of icing I can get out of this tub. I've only used enough for one cake, so I really don't want to take a chance on contaminating the good stuff.

First you need to find the weight of one cup of icing.
Place the container you will measure 1 cup of icing in on your scale and zero out the scale. This will take in to account the weight of the container so all you have to do is add the icing and get the weight of it.

Let's call the weight of 1 cup of icing x lbs

# of cups of icing per container = 24 lbs / x lbs

Price per cup = $40/ number of cups of icing per container.

So, let's assuming the following:

1 cup of icing = 0.5 lbs = 227 g

number of cups = 24 lbs /0.5 lbs
= 48 cups of icing per container

OR using metric

number of cups = 10.88 kg/0.227 kg
= 47.9 cups which rounds up to 48 cups

Price per cup of icing = $ 40.00/ 48 cups
=$0.83 per cup of icing.

All of that just confussed the crud outta me lol.... My suggestion would be taking and measuring out the cups one at a time... time consuming, messy and a PITA but could be helpful... doesn't the container state on the back label who many cups is in it? like serving size = 1 cup servings per container = xxx

That's the way I'm thinking. But I don't have a scale! I even threw out my bathroom scale a couple of months ago, because all it ever read was 160. icon_confused.gif

Would anyone with a kitchen scale be kind enough to measure their icing if it is close to the consistency as I described earlier? No back label, all I know is the 24 lbs. I guess because the containers are filled by weight, not volume. (Sounds like the disclaimer on the cereal and Cracker Jack boxes!)

Incase no one else can help you... is calling the company and asking them or even emailing customer support and asking them an option?? I mean someone at the company HAS to know the weight or the cuppage icon_wink.gif (is that a word lmao)
