2-64.

Kimberly is always complaining that it is either too hot or too cold. As a matter of fact, she is so picky that she is only happy when it is *exactly*

Is there a time when Kimberly is happy?

Is it possible for temperature to rise from

F to F without reaching every possible temperature in between F to F ? If at 6:00 p.m. the temp is

F, what is the minimum number of times Kimberly was happy today? At 8:00 am, it was

F.

At 3:00 pm, it wasF.

At 6:00 pm, it wasF.
