Discount stores sell relatively elastic goods. Certeris paribus, explain why selling at a relatively low price is profitable for them

A slight increase in price will result in more than proportionate decrease in revenue

Explanation:

All other things being equal, if demand for a product is relatively elastic, then the proportionate change produced in demand is greater than the proportionate change in price of a product.

Since Discount stores sell relatively elastic goods, it is profitable to sell at a relatively low price.

The reason is that, a slight increase in price will lead to more than proportionate reduction in quantity demanded thereby leading to a drastic drop in revenue for Discount Stores
