The Larvine family was on a tight budget, but they loved Japanese food. Every Friday, the family of five ate dinner at the only Japanese restaurant in town.

Which of the following BEST restates the point made in the statement below? "The most famous law in economics, and the one economists are most sure of, is the law of demand.

A change in the cost of an imputes can decrease quantity supplied. As the supply curve shifts to the left suppliers raise their prices, and the quantity demanded falls.

consumers purchase Z-Balls rather than the brand they normally buy
Which of the following BEST explains how the situation shows in the graph affects producers and consumers? (surplus graph) a. it benefits the producer, because the higher price increases profits b. it benefits the consumer, because the price must come down to reach equilibrium c. it benefits the consumer, because the quantity supplied is greater than the quantity demanded d. it benefits neither, because consumers must pay more and producers must throw out excess supply
it benefits neither, because consumers must pay more and producers must throw out excess supply
