The city of Stafford has been one of the world's biggest makers of cough drops for many years. But last month, Stafford's cough drop factories were destroyed by floods. What will probably happen to the overall supply of cough drops?
The supply will probably go up. The supply will probably go down.
Overall supply is the total amount of a good or service that producers make and sell. There are several things that can make overall supply go up or down. The table below shows how changes to these things might affect overall supply.
 | Resources | Number of producers or suppliers | Expected change in demand
Supply goes up | when resources cost less or are easier to get | when there are more producers or suppliers | when demand is expected to go up
Supply goes down | when resources cost more or are harder to get | when there are fewer producers or suppliers | when demand is expected to go down
Producers are people or companies that make goods or provide services. Suppliers are people or companies that sell goods or services. New inventions or technologies can also help workers produce goods and services more quickly. As a result of these changes, the supply of a good or service will often go up.
Floods destroyed the cough drop factories in Stafford. The number of producers of cough drops went down. So, the supply of cough drops will probably go down.
