Steve and Craig have been shipwrecked on a deserted island in the South Pacific. Their economic activity consists of either gathering pineapples or fishing. Steve can catch 4 fish in 1 hour or harvest 2 baskets of pineapples. At the same time, Craig can

reel in 2 fish or harvest 2 baskets of pineapples. If they each spend four hours a day fishing and four hours a day harvesting pineapples, what will their total production be? If Steve only catches fishes and Craig only harvests pineapples, how will total production change?

Steve produces 16 fish per day (4 hours × 4 fish per hour) and 8 baskets of pineapples (4 hours × 2 baskets per hour). Craig produces 8 fish per day (4 hours × 2 fish per hour) and 8 baskets of pineapples (4 hours × 2 baskets per hour). Total production is 24 fish per day and 16 baskets of pineapples.
If Steve only catches fishes and Craig only harvests pineapples, total production will increase.
