Background Layout Theme Transition 2 A hot air balloon travels up to 7500 feet. After exploring the sky for a few hours it desce
nds to 3000 feet before making its final descent back to earth Joe used the following expression to represent the total distance the hot air balloon descended. 7500 - (-3000) Is this expression correct? Explain your answer.
This is incorrect because the hot air balloon traveled up to 7500 feet. The distance descended cannot be greater than 7500 feet. Joe's expression tells us that the hot air ballon descended 10500 feet. He is incorrect because 10500 > 7500.
