Question 146153
a coffee manufacturer wants to market a new blend of coffee that sells for $3.90 per pound by mixing two coffees that sell for $2.75 and $5.00 per pound, respectively.
 What amounts of each coffee should be blended to obtain the desired mixture? [Hint: Assume "a" and "b"
-----------------
Quantity equation: a + b = 100 lbs
Value equation: 2.75a + 5b = 3.90*100
-------------------------------------
Solve by any means to get:
a = 48.89 lbs (amt of 2.75 coffee in mixture)
b = 51.11 lbs (amt of $5 coffee in mixture)
