10. The distance in miles from the airport that a plane should begin descending, divided by 3, equals the plane's
height above the ground in thousands of feet. If a plane is 10,000 ft above the ground, write and solve an equation
to find the distance at which the pilot should begin descending.

Hi there!

Let t be the number of teachers
Let a be the number of administrators

t+a=24
35,000t+40,000a=860,000
a=24-t
35,000t+40,000(24-t)=860,000
35,000t+960,000-40,000t=860,000
35,000t-40,000t=860,000-960,000
-5,000t=-100,000
t=-100,000/-5,000
t=20
a=24-t
a=24-20
a=4

Therefore there are 4 administrators and 20 teachers. 

Hope this helps!
