----------------
Equation:
Quantity:: c + a = 100 lbs
Value:: 190c + 120a = 148*100 cents
------------------------------------------
Modify for elimination:
190c + 190a = 190*100
190c + 120a = 148*100
-------------------
Subtract and solve for "a"::
70a = 22*100
a = 31.43 lbs (amt. of almonds needed)
