Answer:
1st one
Step-by-step explanation:
Supply and Demand: The lower the supplies a store can offer, the higher the demand of the people become. And the higher the prices go.
Ex: During Hurricane Irma people needed gas for there cars. As people used gas, gas companies became low on gas. The store workers increased the price of gas for the people so they could get more gas to provide. Since we needed gas at the time, people were willing to pay more for gas.
