Let a and c represent the numbers of adult and children's tickets sold, respectively. The system of equations will have one equation for revenue and one equation for number of tickets.
The revenue equation is
18a +9c = 4959
The number of tickets equation is
a + c = 319
_____
The solution can be found any number of ways. It is
(a, c) = (232, 87)
(17.16-13)/13=0.32=32%
the percent of change=the amount of change/the original number

Choice A) This is false. Arc AC is 180 degrees while arc AB is 90 degrees.
Choice B) This is true. These segments are radii
Choice C) This is true. AB is 90 degrees and so is BC.
Choice D) This is true due to Thales Theorem.
--------------------------------------------------------------------
The only answer choice that is false is choice A.
Therefore, the final answer is choice A
