Question

A hot air ballon was 240 ft above the ground. It decreased its altitude by 6 1/2 ft per min for 15 min, and then increased its altitude by 9 ft. What was the ballon’s overall change in altitude?? Part A write an expression to model the situation. Part B answer. Part C what is the air ballon’s elevation. PLZZ I will give you 100 points

Answer 1

the altitude is 133.5 but I was beat to this bc I was playing gta

Answer 2

Part A The equation to model this would be

240-( 240- 6.5x + 9) = y

x is the minutes the balloon decreases in altitude

Part B plug in x

240- (240 - 6.5(15) + 9) = y

y = 106.5

expression answer: 106.5

Part C altitude is 133.5 (240 - 106.5)
