A university's library checks out books for a 4-week period, but allows them to be renewed up to 5 times. What is the maximum number of weeks the library will allow a book to be checked out continuously?
Show answer & explanation
Answer: A. 24
The initial checkout period is 4 weeks. With 5 renewals, each extending the period by another 4 weeks, the total is 4 + (5 × 4) = 4 + 20 = 24 weeks. The book can be held continuously for a maximum of 24 weeks.
Step-by-step Derivation:
Initial checkout: 4 weeks
Number of renewals allowed: 5
Each renewal adds: 4 weeks
Total = Initial checkout + (Number of renewals × Weeks per renewal)
Total = 4 + (5 × 4) = 4 + 20 = 24 weeks
