Explanation:
Let
x -----> the number of student tickets
y -----> the number of adult tickets
we know that
The number of student tickets multiplied by it' s cost ($5) plus the number of adult tickets multiplied by it' s cost ($10) must equal $3,000
so
The linear equation that represent this situation is
