Final answer:
A fall in demand is most likely to explain the outcome of more computers being sold at lower prices in the computer market.
Step-by-step explanation:
The shift in demand that is most likely to explain the outcome of more computers being sold at lower prices in the computer market is a fall in demand.
When there is a fall in demand, the quantity demanded decreases at any given price level. This leads to a surplus of computers in the market, causing sellers to reduce the prices in order to sell the excess inventory.
A demand and supply diagram can help illustrate this. On the diagram, the demand curve would shift to the left, indicating a decrease in demand. The equilibrium price and quantity would decrease, showing the lower prices and higher quantity of computers being sold.
