Question

Explain how to find n, the number of copies the machine can print in one minute. I need an algebraic expression for the answer.

Once the first part is done, I need help with this question.

Working at the same rate, how long will it take the machine to print 5,200 copies? Explain how you found your answer.

Answer 1

It will take 80 minutes!

Explanation:

From the table we see that in 5 minutes we get 325 copies.

This means in one minute we get
`$ (325)/(5) $` = 65 copies.

So, assume we get 5200 copies in 'x' minutes.

So, we form the equation.

i.e., 65x = 5200

⇒ x = 80

This means it would take 80 minutes to get 5200 copies.
