Question 758598
The Golden Cup Coffee Shop sells Hawaiian Kona coffee for $36.50 per pound
and Sulawesi Kalossi coffee for $13.00 per pound . 
The coffee shop also makes a homemade blend of 
these two coffees that sells for $20.52 per pound (obviously a high-end coffee shop!!). 
How much of each coffee should they blend together to make a 100 lb bag of the blend?
-----
Equations:
Quantity Eq::: H + K = 100 lbs
Value Eq::::36.50H + 13.00K = 20.52*100 dollars
----------------------------------------------------
Modify for elimination:
1300H + 1300K = 1300*100
3650H + 1300K = 2052*100
--------------------------------
2350H = 752*100
H = 32 lbs (amt. of Hawaian coffee needed)
------
Solve for "K":
H + K = 100
K = 68 lbs (amt of Kalossi coffee needed)
