Answer:

-7^{\circ}F

Step-by-step explanation:

Let x represent temperature change per hour.

We have been given that the temperature is going to steadily drop over the next 4 hours and the temperature changes by the same amount each hour.

So temperature change in 4 hours would be 4x.

We are also told that the temperature changes by a total of -28°F, so we can represent this information in equation as:

4x=-28^{\circ}F

Let us solve for x.

\frac{4x}{4}=-\frac{28^{\circ}F}{4}

x=-7^{\circ}F

Therefore, the temperature changes -7^{\circ}F each hour.
