Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `integer`

→ Used by:

cost
defs

Statement
Advice

Information only

Ask the student a question, and give any hints about how they should answer this part.

Write down an equation to calculate the cost, $C$ of hiring the {job} for $h$ hours.

Once you have completed the whole question, you can click on "Reveal answers" to check your equation.

Advice

An equation for the cost of hiring the plumber for $n$ hours is:

$C = \var{rate} n + \var{callout}$

For $\var{n}$ hours, it will cost $C = \var{rate} \times \var{n} + \var{callout} =$ {costdollars}

Your graph should look similar to this {geogebra_applet('https://www.geogebra.org/m/wxv4ykqj',defs)}

Your graph needs:

to start at (0,0).
to show the line.
to contain the point $(\var{n},\var{cost})$ and the point $(0,\var{callout})$
labels and arrows on both axes. In this graph, the horizontal axis is labelled $x$. However, you should have labelled yours as $n$ or $time (hours)$. In this graph, the vertical axis is labelled $y$. However, you should have labelled yours as $C$ or $Cost (\$)$.
a scale on each axis.

You may have chosen different scales for your axes. This is fine.

Give a worked solution to the whole question.
