Chapter 0.4, Problem 5E

a.

To determine

Complete the table.

Answer to Problem 5E

Number of Ticket	1	2	3	4	5
Total Cost ($)	6.50	13	19.5	26	31.5

Explanation of Solution

Given information: The cost of one ticket $ 6.5.

Number of Ticket	1	2	3	4	5
Total Cost ($)	6.50

From the above table if cost of one ticket is $ 6.5 then cost of 2 tickets is $\left(\$6.50+\$6.50=\$13\right).$

Similarly for 3 tickets $\left(\$6.50+\$6.50\text{ + \$ 6}\text{.5}=\$\text{ 19}\text{.5}\right).$

Therefore, $\text{Cost of Tickets }=\text{Number}\text{of}\text{Tickets}\times \text{6}\text{.5}$

Number of Ticket	1	2	3	4	5
Total Cost ($)	6.50	13	19.5	26	31.5

b.

To determine

Find the relation between the number ticket and cost of the ticket.

Answer to Problem 5E

The cost of the ticket is $ 6.5 times the number of ticket.

Explanation of Solution

Given information: The cost of one ticket $ 6.5.

Number of Ticket	1	2	3	4	5
Total Cost ($)	6.50

From the above table if cost of one ticket is $ 6.5 then cost of 2 tickets is $\left(\$6.50+\$6.50=\$13\right).$

Similarly for 3 tickets $\left(\$6.50+\$6.50\text{ + \$ 6}\text{.5}=\$\text{ 19}\text{.5}\right).$

There is a relation between the ticket and cost of the ticket that cost of the ticket is 6.5 times the number of ticket.

Therefore, $\text{Cost of Tickets }=\text{Number}\text{of}\text{Tickets}\times \text{6}\text{.5}$

c.

To determine

Have to find the cost of 8 tikets.

Answer to Problem 5E

The cost of the 8 tickets are $ 52.

Explanation of Solution

Given information: The cost of one ticket $ 6.5.

Number of Ticket	1	2	3	4	5
Total Cost ($)	6.50

From the above table if cost of one ticket is $ 6.5 then cost of 2 tickets is $\left(\$6.50+\$6.50=\$13\right).$

Similarly for 3 tickets $\left(\$6.50+\$6.50\text{ + \$ 6}\text{.5}=\$\text{ 19}\text{.5}\right).$

There is a relation between the ticket and cost of the ticket that cost of the ticket is 6.5 times the number of ticket.

Therefore, $\text{Cost of Tickets }=\text{Number}\text{of}\text{Tickets}\times \text{6}\text{.5}$

Now, the cost of 8 tickets $=8\times 6.5=\$52$
