Step 1: In the combination of 100 pounds, let there be x pounds of Arabic.
Step 2: So, the combination has (100 - x) pounds of Brazilian
Step 3: Cost of the mixture = cost of arabic in mix + cost of brazilian in mix
=
Step 4: But the cost of the mixture is given to be 20 per pound. Or, cost of 100 pounds of mix =
Step 5: The values of step 3 and step 4 have to be equal. Hence we have the equation

Step 6: Solve for x

So the mixture has pounds of Arabic and pounds of Brazilian coffee.
