o.k. i was originally going to PM Calesta this math problem, due to the fact i know he is good with it. BUT, i then thought of the fact that some people actually like doing math. (im not one of them)
My little brother emailed me with a intermediate algebra problem.
i received a "c" in algebra and for the life of me, i cannot figure out how to set up the equation for this problem. i remember how to solve equations, but i am no good at setting them up....
So, i decided to post it on here, and if you like doing math, then eat your little heart out. also, can you give an explanation as to why you set up the equation the way you did?
----------------------------------------------------------------------------------------------
Suppose that you have a supply of a 30% solution of alcohol and a 70% solution of alcohol. How many quarts of each should be mixed to produce 20 quarts that is 40% alcohol.
----------------------------------------------------------------------------------------------
and before you flame me because this is a "easy problem"
i majored in English and could write you a paper that would
be worthy of a Pulitzer ....
but i suck at math.
My original answer to mike (my brother) was kill the (.3 and .7 which represent percentages) DECIMALS <EDIT>>by multiplying by 10.
so:
(30x)+(70x)=40(20)
which obviously was wrong. i dont think 30 and 70 can share the same variable?
