Albert bought 2 pounds of catfish and 2 pounds of salmon

Let c represent the amount of catfish in pounds and s represent the amount of salmon in pounds.

He spent a total of $12 on salmon and catfish and bought a total of 4 pounds. Hence:

c + s = 4 (1)

4c + 2s = 12 (2)

Solving equations 1 and 2 simultaneously gives:

c = 2, s = 2
