Answer:
inferior, normal
Step-by-step explanation:
Consumers tend to spend more or less on a commodity when their income level changes. This is as a result of preference that is restricted by income level.
Based on this there are 3 types of goods: inferior, normal, and necessity.
Inferior goods are ones that a consumer will abandon for other goods when income rises.
Normal goods are the ones where demand increases as income rises.
Necessity are goods whose demand remains constant despite income changes.
