Chapter 6, Problem 18MCQ

To determine

To calculate:

The museum admission costs for a specific group of students as given in the table at the rate of $2 per student.

Answer to Problem 18MCQ

Required table is filled as:

No. of students	5	10	15	20	25
Cost ($)	10	20	30	40	50

Yes. Pattern surely forms a proportion because each ratio between number of students and its corresponding cost is $\frac{1}{2}$ .

Explanation of Solution

Given information: 

The admission rate of one student in the museum is $2 and Mr. Dexon has 25 students in his fine art`s class.

Formula used:

  $\text{Total cost of students }=\text{cost per student }\times \text{ total number of students}$

Calculation:

Required cost for said group of students is calculated as :

No. of students	5	10	15	20	25
Cost ($)	$5\times 2=10$	$10\times 2=20$	$15\times 2=30$	$20\times 2=40$	$25\times 2=50$

Conclusion: From above values it is cleared that:

  $\frac{\text{No}\text{.of students}}{\text{their cost}}=\frac{5}{10}=\frac{10}{20}=\frac{15}{30}=\frac{20}{40}=\frac{25}{50}=\frac{1}{2}$

Or as corresponding ratio is equal, so this pattern is surely in proportion.
