Question

a rightward shift of a supply curve would result from: lower production costs. a decrease in the price of the product. fewer sellers of the product. an increase in the price of an alternative - product that could be produced with the same resources.

Explanation:

A right - ward shift of the supply curve means an increase in supply. Lower production costs allow producers to supply more at each price level. A decrease in product price leads to a movement along the supply curve, not a shift. Fewer sellers reduce supply (left - ward shift). An increase in the price of an alternative product causes producers to shift resources to produce the alternative, reducing supply of the original product (left - ward shift).

Answer:

lower production costs.
