A household must insert compatible coffee pods into a pod coffee machine to make coffee. The price of pod coffee machines rises.
Name the relationship between pod coffee machines and compatible coffee pods.
Table 1 shows two possible effects on the demand curve for compatible coffee pods.
| Change | Possible effect |
|---|---|
| A | A movement upwards and to the left along the existing demand curve |
| B | A shift of the demand curve to the left |
Explain whether Change A or Change B shows the likely effect of the rise in the price of pod coffee machines.
