Answer: 9 hours

Step-by-step explanation:

The inequality that shows the minimum number of hours, n, that Angela should work as a babysitter to earn enough to buy a series of books is:

4n + 24 ≥ 60

Step-by-step explanation:

4n represents the amount of money Angela earns as a babysitter for n hours.

24 is the amount of money Angela already has saved.

The sum of these two amounts (4n + 24) must be greater than or equal to the cost of the books, which is $60.

Simplifying the inequality:

4n + 24 ≥ 60

4n ≥ 36

n ≥ 9

Therefore, the minimum number of hours Angela should work as a babysitter to earn enough to buy a series of books is 9.
