So we have ave a math problem that we are arguing on. This started as an argument between two 40 year olds looking through kid's math books. Here is the problem:
If there is 26 times more caffeine in a normal cup of coffee than in decaf and the total between them is 121.5 Grams of caffiene, how much is in each cup?
While I have no clue how to solve it, I can verify answers (Thank god my old brain retains that ). My logic says that:
Decaf + Regular = 121.5
Decaf * 26 = Normal
He is trying to tell me that Decaf = 4.67 and Caffien = 116.82. Rounded of course.
I can tell this is wrong because while Decaf + Regular is true, Decaf * 26 is not.
How can I prove him wrong here?
