Let the number of weeks to have same amount = x Then:-
1200 + 40x = 700 + 50x

Answer:
Correct answer is D(the intersection of lines N and M)
Step-by-step explanation:
we Know that circumcenter of a triangle is point at which the perpendicular bisectors of the sides of a triangle intersect and which is equidistant from the three vertices. In other words circumcenter of a triangle is the center of the circle which passes through the vertices of the triangle. It means, any side of the triangle will act as a chord of the circumcircle. Hence the circumcenter of a triangle must lie on the perpendicular bisectors of the sides. therefore the intersection of line N and M must be circumcenter of the triangle.
I hope this answer will help you
