a copy machine makes copies at a constant rate. the machine can make 80 copies in 2 minutes.

a. write an equation to represent the number of copies, n, that can be made over any time interval in minutes, t

b. complete the table below.

t (time in minutes)

n (number of copies)

linear equation:

0.25

0.75

( You copied the question worng , it is 80 copies in 2 1/2 minjtes , not 2 minutes )

If the machine takes 2 1/2 minutes to make 80 copies , it would take 1 minute to make 36 copies. With that information ww can make the equation :
5/2n = 80t
Isolate t by dividing both sides of the equation by 5/2:
(5/2)/(5/2)n = 80/(5/2)t
(5/2)/(5/2) = 1 so we end up with:
n/1 = 32t
n = 32t
So what that means is that the machine can make 32 copies per minute

Awnser : a) n = 32t
b) t , Linear equation , n
.25, y = 32x, 8
.5, y = 32x, 16
.75, y = 32x, 24
1 , y = 32x, 32
( As the rate stays the same , the linear will stay the same !)

I hope you understood my brief explanation. And please consider marking this awnser as Branliest if ypu think it deserves it. Thank you ! :)

15 dimes at 15x10=$1.50
12 nickels at 12x5=$0.60
$1.50+0.60=$2.10
So Alexandra has 15 dimes and 12 nickels
