Explanation:
Let
x -----> the number of adult tickets
y -----> the number of children's tickets
we know that
The algebraic expression that represent the total amount of money raised from the sale of tickets is
![7x+2y](https://img.qammunity.org/2020/formulas/mathematics/middle-school/g1q1qybr5bxto31fbwllth3sw0ym9wr0l8.png)
For x=234, y=388
substitute in the algebraic expression
![7(234)+2(388)=\$2,414](https://img.qammunity.org/2020/formulas/mathematics/middle-school/c7fqom5ubu5021qatiz82q1pwqxzpf27g3.png)
