Chapter 14, Problem 44CCSR

Solution

To find: How many adults tickets were sold?

Hence, option C is correct.

Given: A high school sold 800 tickets for a soccer game. Three types of tickets were sold, adult, student and child.

Concept Used: Methods of solving linear equation in one variable

Calculation:

Total number of tickets are 800.

Let the number of child tickets be $x$ .

Number of adults tickets are $4x$ .

Number of students tickets are $4x+62$

  $\begin{array}{c}x+4x+4x+62=800\\ 9x=800-62\\ x=\frac{738}{9}\\ x=82\end{array}$

Number of adults tickets are $4\times 82=328$

Conclusion:

Hence, option C is correct.
