Question

# The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of \$38. The school took in \$52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Which system of equations can be used to determine s, the number of senior citizen tickets sold and c, the number of children tickets sold?

Hint:

## The correct answer is: 3s + 1c = 383s + 2c = 52

### Now we know that one, two, or three variables may be present in a linear equation. As a result, we are able to formulate linear equations with n variables.Here we have given that the school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of \$38. The school took in \$52 on the second day by selling 3 senior citizen tickets and 2 child tickets. So let number of senior citizen tickets be denoted as s, and c be the number of children tickets.Then system of equations are,3s + 1c = 383s + 2c = 52

So here we used the concept of system of equations in two variable. Here in the question the variable quantity was 2 so two variables are there. So the system of equations are: 3s + 1c = 38, 3s + 2c = 52
