The temperature is 50°F The temperature will decrease by 4°F each hour. Let

h be the number of hours,

When will the temperature be below 32°F?

Write an inequality for this problem,

A. 50 - 4h: 32

B. 50 - 4h32

c. 50 + 4h3 32

D. 50 + 4h + 32

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
