Answer: Change in income, inferior good, normal good

Explanation: Andrew consumed bean-lightened coffee when he had no income. But when he got the job paying him $75,000 a year he shifted his demand to consuming Starbucks even though it costed more than bean-lightened. This change in demand is solely due to a rise in income.

When demand for a good decreases with an increase in income, they are termed as inferior goods. In this case, Bean-lightened coffee is an inferior good for Andrew since he consumed more at Starbucks when his income increases. Starbucks is therefore a normal good for Andrew since an increase in income leads to an increase in quantity demanded at Starbucks.
