The members increased their elevation 290 feet during their hike this morning. Now they are at an elevation of 450 feet. A. Explain how to find their elevation before the hike.
B. Han says the equation e + 290 = 450 describes the situation. What does the variable e represent?
C. Han says that he can rewrite his equation as e = 450 + -290 to solve for e. Compare Han's strategy to your strategy for finding the beginning elevation.
