-------------------
Equations:
Quantity Eq: n + o = 29
Value Eq::145n+105o = 125*29
----------------------------------
Multiply thru Quantity by 145
-----
145n + 145o = 145*29
145n + 105o = 125*29
------
Subtract and solve for "o":
40o = 20*29
o = 29/2 = 14.5 lbs (amt. of oats needed)
----
Solve for "n":
n + o = 29
n + 14.5 = 29
n = 14.5 lbs (amt. of nuts needed)
