Question 718897
<font face="Times New Roman" size="+2">


You won't be able to actually solve this one because you are missing a vital piece of information, namely the total cost of the bag of cookies.


If there are *[tex \LARGE x] of one type of cookie and *[tex \LARGE y] of the other type and there are a total of *[tex \LARGE 45] cookies, you can write:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ y\ =\ 45]


And if you happened to know that the entire bag of cookies was worth *[tex \LARGE $T] total, then you could write:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 3x\ +\ 5y\ =\ T]


then, given that you know the value of one of those variables, that is either *[tex \LARGE x], *[tex \LARGE y], or *[tex \LARGE T] you could use the system of equations to find the value of the two variables that you don't know.  But, since you can only form two equations and you need three pieces of information, you are pretty much done.
