Question

I’m confused on how to start. I also need help with what goes in the boxes. I think i can do the graph

Answer 1

The total cost has two parts:

- a fixed one for the entry, $5

- a variable one, $1 per ticket.

If y is the total cost and x is the number of tickets, then y will be the sum of the fixed cost and the variable cost multplyied by the number of tickets, x.

That is, the equation is:

`\begin{gathered} y=1\cdot x+5 \\ y=x+5 \end{gathered}`

Using this equation, we can calculate y for each x in the table.

For x = 0:

`\begin{gathered} y=0+5 \\ y=5 \end{gathered}`

For x = 1:

`\begin{gathered} y=1+5 \\ y=6 \end{gathered}`

For x = 2:

`\begin{gathered} y=2+5 \\ y=7 \end{gathered}`

For x = 5:

`\begin{gathered} y=5+5 \\ y=10 \end{gathered}`

So, the table is:

x | # tickets | 0 | 1 | 2 | 5

y | cost | 5 | 6 | 7 | 10

For the graph, we can plot at least two of these points and connect them to form a line:
