Step-by-step explanation:

Here, h be the number of hours.

As per the statement:

The temperature is 50 degrees Fahrenheit.

⇒Initial temperature = 50 degrees Fahrenheit

It is also given that:

The temperature will decrease by 4 degrees F each hour.

1 hour temperature will be = -4 degree F

then;

In h hour temperature =  -4h degrees F

We have to find the the temperature be below 32 degrees F.
