Question

yesterday the temperature at noon was 16.8F. By midnight it had dropped by 20.1FWhat was the temperature at midnight

Answer 1

If we know that the temperature dropped by 20.1 F, we substract that amount from the initial 16.8 F

`16.8F-20.1F=-3.3F`

This way, we can conclude that the temperature at midnight was -3.3 F
