in symbols, C means concentration,A is the amountof substacesand T os the total quantity.
if 8 ounces of punch contains 4 ounces of pure pineapple juice,the concentration of pineapple juice in the punch is
[tex] \binom{4}{8} [/tex]
or 0.5 or 50%.The punch is 50% pineapple juice.
Consider the problem where we begin the 8 ounces of punch that is 50% pineapple juice and want to write a function that gives the pineapple juice concentration after x ounces of pure pineapple are added:


[tex]c = \frac{a}{t} [/tex]
