An airplane is flying at 20,000 ft and needs to ascend up to 35,000 ft to avoid a storm that is up ahead. The plane rises at a rate of 3,000 ft per minute. Which equation shows the height H of the plane after x minutes

• H = 3,000x + 20,000

• H = 3,000x + 35,000

• H = 20,000x + 3,000

• H = 35,000x + 3,000
