Show answer & explanation
Answer: B. B) Nine
Rogers = 5. Miller = 15 > Kemp + Rogers => Kemp < 10. Calvin = 8 < Kemp => Kemp > 8. Since 8 < Kemp < 10, Nurse Kemp has worked 9 night shifts.
Step-by-step Derivation:
Step 1: Rogers = 5.
Step 2: Miller = 15 > Kemp + 5 => Kemp < 10.
Step 3: Calvin = 8 < Kemp => Kemp > 8.
Step 4: Since Kemp must be an integer: 8 < Kemp < 10 => Kemp = 9.
