Answer:
July has the highest attendance.
Explanation:
The attendances are expressed in scientific notation where the second term, 10^x, means 10 to the xth power. For example 10^1 = 10, 10^2 = 10*10 = 100 and so on.
Looking at the table, July's attendance has the highest power, 10^6 while other months only have 10^5. So July has the highest attendance.
