Suppose the market for flip-flops is in equilibrium. If a new machine is created to mold the shoes for a lower cost, then we would expect to see a(n): a. increase in supply b. increase in quantity supplied c. decrease in supply d. decrease in quantity sup

The answer is a. increase in supply. When a new machine is created to mold flip-flops for a lower cost, it reduces the cost of production for suppliers. As a result, suppliers can supply more flip-flops at a lower price without sacrificing their profit margin. This will lead to an increase in the quantity of flip-flops supplied and shift the supply curve to the right, resulting in a lower equilibrium price and a higher equilibrium quantity. Therefore, the correct answer is an increase in supply.
