On a mountain, the temperature decreases by 18 F for each 5000 foot increase in elevation. At 7000 feet, the temperature is 41 F. What is the temperature at 22,000 feet?

Step-by-step explanation:

To find this answer, use multiples. For every 5000 feet ascended, deduct 18 degrees. For 20,000 feet, which is (4 * 5000), use (4 * -18). In this case, the answer is -72 degrees F, so the integer described would be -72.
