Question

Tickets are $4.50 for adults and $2.50 for students. If total of 230 tickets are sold for $825, how many student tickets were sold?

Answer 1

Answer:

The number of student tickets sold was 105

Step-by-step explanation:

Let

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

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

we know that

If total of 230 tickets are sold for $825

then

$x+y=230$ ----> equation A

$2.50x+4.50y=825$ ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

using a graphing tool

The solution is the point (105,125)

see the attached figure

therefore

The number of student tickets sold was 105
