Quizplus · Accepted Answer

To determine the change in market quantity supplied, we need to sum up the quantity supplied by each seller at both prices. At $4, the market quantity supplied is 10+20+30+40 = 100 units. At $2, the market quantity supplied is 5+10+15+20 = 50 units. Therefore, the market quantity supplied decreases by 50-100 = -50 units, which is a decrease of 10 units per seller. So the correct choice is B, which is a decrease of 10 units.
