Problem
recorded. What is the day it was $136^{\circ} \mathrm{F}$. In the Gobi Desert a temperature of $-50^{\circ} \mathrm{F}$ was recorded. What is the difference between these two temperatures? The diver descended 15 feet below the surface of the water. Then she went down 20 more feet. What was her final elevation?
Solution
Step 1 ：Find the difference between the high and low temperature: \( 136 - (-50) \)
Step 2 ：\( 136 + 50 = 186 \)
Step 3 ：\(\boxed{186}\)
