Answer:
B
Step-by-step explanation:
It helps if you have the figure included. However, since it is not, we can assume that she has gone around the circle with all six sides of the hexagon is set to PR.
That makes the hexagon with 6 equal sides. It also makes each triangle using one of the sides equal to PR. The radii are all equal. There are 6 triangles making up the hexagon.
Both statements she makes are true and that makes B the answer.
I hope this helps you
adult=a
children's =500-a
17.95×a+12.95×(500-a)=7355
17.95a+6475-12.95a=7355
5a=880
a=176
