Question 894030
Very similar to problem request 893672 from here:
<a href="http://www.algebra.com/algebra/homework/word/coins/Word_Problems_With_Coins.faq.question.893672.html">http://www.algebra.com/algebra/homework/word/coins/Word_Problems_With_Coins.faq.question.893672.html</a>
Same problem but just different example.


Without using a general solution,
u = pounds of the cheap coffee, type A
v = pounds of the expensive coffee, type B


ACCOUNT FOR COST OF BLEND USING THE GIVEN PRICES: {{{4.60u+v5.95=830.65}}}
 and 
SHOW THE RATIO OF TYPE B TO TYPE A COFFEES ACCORDING TO THE DESCRIPTION:  {{{v/u=3}}}.


The question asks for the value for u.
<b>Here is MOST of the way to solving for u.</b>
{{{v=3u}}};
substitute;
{{{4.60u+5.95(3*u)=830.85}}}.
Just solve this for u.
