To form 100 lb of the mixture we need 25 lbs of $9 coffee beans and 75 lbs of $15 coffee beans.
Step-by-step explanation:
Let <em>x</em> be the number of pounds of $9 coffee beans and y be the number of pounds of $15 coffee beans.
We know that the mixture must weigh 100 lb

and the total cost per pound is given by

Now, we can solve the system of equations

Isolate x for 

Substitute
into the second equation

Isolate y

For
substitute y = 75

To form 100 lb of the mixture we need 25 lbs of $9 coffee beans and 75 lbs of $15 coffee beans.
