Answer:
1,800 copies.
Explanation:
The monthly fixed charge of renting the photocopier = $20
Cost for each copy = $0.02
If Jamie makes x copies, his cost will be $0.02x.
Therefore, his monthly bill will be:
[tex]\begin{gathered} \text{Monthly Bill=Fixed Charge+Cost of x copies} \\ y=20+0.02x \end{gathered}[/tex]
If Jamie's monthly bill was $56, we have:
[tex]56=20+0.02x[/tex]
We then solve for x, the number of copies made.
[tex]\begin{gathered} 56-20=0.02x \\ 36=0.02x \\ \frac{36}{0.02}=\frac{0.02x}{0.02} \\ 1800=x \\ \implies x=1800 \end{gathered}[/tex]
Jamie was charged for 1,800 copies.
