Problema Solution
To qualify for Gold status at Awesome Airlines, one must fly at least 9000 and less than 23000 miles each year. If Greg takes a 500-mile round trip flight to visit his parents, how many times does Greg need to visit his parents each year to attain Gold status? Enter your answer in interval notation.
Answer provided by our tutors
let 'x' represent the time Greg needs to visit his parents
9000 <= 500x < 23000 divide both sides by 500
9000/500 <= x < 23000/500
18 <= x < 46
X is in the interval [18, 46).
