5c+10a=3570 c+a=512 ... a=512-c so ... 5c + 10(512-c)=3570

Answer:

The system of equations is equal to

a+c=512

5c+10a=3,570

The number of adult tickets sold is a=202\ tickets

The number of student tickets sold is c=310\ tickets

Step-by-step explanation:

Let

c------>  the number of student tickets sold

a----->  the number of adult tickets sold

we know that

a+c=512 -----> equation A

5c+10a=3,570 -----> equation B

Using a graphing tool

The solution of the system of equations is the intersection point both graphs

see the attached figure

The intersection point is (202,310)

therefore

the solution is

the number of adult tickets sold is a=202\ tickets

the number of student tickets sold is c=310\ tickets
