Answer to Problem 8MCQ

The total cost for admission of 2 adult, 3 children and 2 senior is $\$30$ .

Explanation of Solution

Given:

For pool admission:

Adult costs: $6

Children cost: $4

Seniors cost: $3

Calculation:

Suppose x is cost adult,y be cost for children and z be the cost for seniors.

So,

Expression for pool admission becomes;

  $\text{F}\left(\text{n}\right)=6\left(\text{n}\right)+4\left(\text{n}\right)+3\left(\text{n}\right)$

So,

For 2 adult, 3children and 2 seniors;

Total cost:

  $\begin{array}{l}\text{F}=6\left(\text{2}\right)+4\left(\text{3}\right)+3\left(\text{2}\right)\\ \text{F}=12+12+6\\ \text{F}=\$30\end{array}$

The total cost for admission of 2 adult, 3 children and 2 senior is $\$30$ .
