    Answer:

    50-4h<32

    Step-by-step explanation:

    If the temperature starts at 50 and the temperature is decreased by 4 per each hour, then:

    1) after the first hour, the temperature is 50-4 or 46

    1) after the second hour, the temperature is 46-4 or (50-4)-4 or 50-4(2).

    So what I’m trying to show you that if I continue this pattern our equation for what happens h hours later is: 50-4h.

    We want to know when is the temperature below 32 so less than 32.

    Temperature<32

    Put in our variable expression for temperature.

    50-4h<32
