Last month 7,482 people visited the local fair. This month, 6,123 people visited the museum. How many more people visited the museum last month than visited this month?
There isn’t enough information to find the answer because the first number is telling how many people visited to local fair last month. If you were to compare the number of people that visited the local fair last month and the number of people that visited the museum this month then the answer would be 1359 but, it’s not asking for that. This is why you cannot solve this problem
