Question

An online ticket broker charges a flat service fee of 6.50 per ticket sold you are interested in the total amount of money you must pay for a given number of tickets

Answer 1

The broker charges $6.50 per ticket, therefore, the total amount will be directly related to the total number of tickets sold.

The two quantities that are changing in the situation are:

`Total\text{ amount, number of tickets.}`

Now, the total amount depends on the number of tickets sold, therefore, if we define

`\begin{gathered} Total\text{ amount=T,} \\ number\text{ of tickets=n,} \end{gathered}`

we can set the following equation:

`T=6.50n.`

Answer:

Part a) Total amount, and the number of tickets.

Part b)

`\begin{gathered} Total\text{ amount =T,} \\ number\text{ of tickets=n.} \end{gathered}`

T is the dependant variable, and n is the independent variable.

Part c)

`T=6.50n.`
