Question

For a certain event, 817 tickets were sold, for a total of $1919. If students paid $2 per ticket and nonstudents paid $3 per ticket, how many student tickets were sold?

Answer 1

Answer: 532

Explanation:

Let x be the number of students and y be the number of non-students.

Then, by considering the given information, we have

`x+y=817-----(1)\\\\2x+3y=1919-----------(2)`

Multiply 2 on the both sides of equation (1), we get

`2x+2y=1634--------(3)`

Subtract (3) from (2), we get

`y=285`

Put the value of y in (1), we get

`x+285=817\\\\\Rightarrow\ x=817-285=532`

Hence, 532 student tickets were sold .
