An Air Force C-17 Globemaster III cargo plane left Hill Air Force Base in Salt Lake City, UT at a height of 4,330 feet above sea level. If the plane climbs at a rate of 360 feet per minute, which function could be used to determine t, the time in minutes it will take the plane to reach its cruising elevation of 13,690 feet above sea level?
13,690 = 360 + 4,330t
13,690 = 360(t + 4,330)
13,690 = 4,330 + 360t
13,690 = (4,330 + 360)t

13,690 = 360 + 4,330t
13,690 = 360(t + 4,330)
13,690 = 4,330 + 360t
13,690 = (4,330 + 360)t

13690 = 4330 + 360t
         t = 26 minutes
