A hot air balloon is cruising at an elevation of 920 feet above sea level. Its elevation decreases by 130 feet in the first hour, and then by 60 in the second hour. What is the resulting elevation of the hot air balloon?
In the first hour, the balloon decreases by 130 feet for a total of 920-130 = <<920-130=790>>790 feet above sea level.
In the second hour, the balloon decreases by 60 feet for a new total of 790-60 = <<790-60=730>>730 feet above sea level. Answer: \boxed{730}.
