To avoid a storm, a pilot of a vintage biplane flies up 2,500 feet, but stays below 32,000 feet. Write and solve an inequality to find the maximum original altitude of the plane. a + 2,500 > 32,000; a > 34,500

a + 2,500 < 32,000; a < 29,500

a + 2,500 < 32,000; a < 34,500

a + 2,500 > 32,000; a > 29,500
