Big book QC question

Hi All,

Could someone please explain this one to me?

I am assuming the grams are the same in the cans. Couldn’t we just assume each can = 10 grams and calculate the per gram cost from there? Wouldn’t B be bigger?

Thanks!

No the assumption need not be always true the answer is D

The question doesn’t say anything about how many grams are in a can. So you can’t assume cost per gram. So the answer is D.
If the question was asking cost per can you could definitively say B because .30<.50.

It could be:
x grams in a can of carrots and onions

Or:
x grams in a can of carrots and y grams in a can of onions.

Plug-in twice and you’ll get different values.
