A commercial aircraft gets the best fuel efficiency if it operates at a minimum altitude of 29,000 feet and a maximum altitude of 41,000 feet. Model the most fuel- efficient altitudes using a compound inequality. x 29,000 and x ≤ 41,000 xs 29,000 and x ≥ 41,000 x≥ 41,000 and x ≥ 29,000 xs 41,000 and x =29,000
