The answer is C. 168 unlimited-ride passes were sold
u+e=282
50u+20e=10,680
______________
-20u-20e=-5640 need to multiply first equation by -20 to eliminate 20
5u+20e=10,680
_____________
30u+0= 5040
30u=5040 now divide by 30
u=5040/30
u=168

From the diagram you can see that we have constructed a right triangle, with height A and base 15.
Length of shadow = 15 feet.
Height of flagpole = A.
We know the angle of elevation is
40
∘
. Using this angle and the tangent ratio, we can find A.
