Question

A copy machine makes copies at a constant rate. The machine can make 80 copies in 2 1/2 minutes.
Write an equation to represent the number of copies, n, that can be made over any time interval, t.

Answer 1

would anyone help me?

Answer 2

"The machine can make 80 copies in 2 1/2 minutes. " Let's simplify that a bit to obtain a nicer-looking unit rate / conversion factor.

\[\frac{ 80.copies }{ 2\frac{ 1 }{ 2 }.minutes}\]

Answer 3

This can be reduced. Converting 2 1/2 into the improper fraction 5/2, divide 80 by 5/2.

What do you get?

Answer 4

32

Answer 5

Yes, 32 copies per minute. Very good.

Answer 6

i still have more

Answer 7

Now let t=time in minutes.

Let C(t) be a function that returns the number of copies made for any time t.

Write the function: C(t)=?

Answer 8

Complete the table below.
t (time in minutes) Linear equation:
n (number of copies)
0
0.25
0.5
0.75
1

Answer 9

Hint: (# of copies as a function of time) = (rate at which copies are made) * (time elapsed)

Answer 10

this is in a chart give em a minite

Answer 11

Please see my previous comment. I need for you to finish writing the function, C(t), that gives the number of copies made as a function of time, t.

Answer 12

Everything OK? I need your participation to continue with this problem solution.

How is the number of copies made, C(t), a function of time, t?
