1. Calculate how many hours passed between her temperature checks. 8 p.m to 8 a.m. is 12 hours.
2. Calculate the total change in temperature. 36 - 54 is -18, so the temperature went down by 18 degrees.
3. We are looking for degrees per hour, so we put derees(18) over hours (12) to get 18/12.
4. Calculate by dividing. The answer is 1.5 degrees per hour.

General Formulas and Concepts:
<u>Algebra I</u>
- Expand by FOIL-ing (First, Outside, Inside, Last)
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x
g(x) = x - 3
<u>Step 2: Find f(x)g(x)</u>
- Substitute: f(x)g(x) = 2x(x - 3)
- Distribute 2x: f(x)g(x) = 2x² - 6x
