Answer:
Answer: E
Step-by-step explanation:
10 bonus points is too little so that could not be the answer
15 is also too little becuase 100 points is 2 nights
300 points is too much as it is 4 nights
30,000 is too much and the reason is because it is again too much
100 points because if you do the maths the user should recive 150 bonus points, but however there is no option for that. But again 300 is too much so if the hotel gives that much points to the user the hotel will lose money because of the free hotel room. So the logical answer is 100 points.
