which of the following influences on selling plans change supply?\n\na. an increase in the number of buyers of soap changes the supply of soap.\nb. a change in the expected future price of soap changes the supply of soap.\nc. a change in the quantity of soap that consumers plan to buy this month changes the supply of soap.\nd. a change in the wage rate of the workers who produce soap changes the quantity supplied of soap.
Answer
Brief Explanations:
- Option A: An increase in the number of buyers affects demand, not supply.
- Option B: A change in expected future price affects producers' decisions. If they expect higher future prices, they may reduce current supply to sell more in the future at a higher price. This changes the supply curve.
- Option C: A change in consumers' planned - buying quantity affects demand, not supply.
- Option D: A change in the wage rate of workers changes the cost of production and thus the quantity supplied (a movement along the supply curve), not the supply itself (a shift of the supply curve).
Answer:
B. A change in the expected future price of soap changes the supply of soap.
