At 8:00am, the temperature was 60F. By 9:00am, the temperature had dropped 4

To figure out the temperature at 9:00 am given that it dropped 4°F, you need to subtract 4°F from the initial temperature of 60°F. Here's how you can calculate it:

1. Start with the initial temperature at 8:00 am: 60°F.
2. Subtract the temperature drop of 4°F: 60°F - 4°F = 56°F.

Therefore, the temperature at 9:00 am would be 56°F.
