Question

the table below shows how long a copier took to make copies.

number of copies	time
2 copies	17 seconds
3 copies	24 seconds
4 copies	31 seconds

fill in the blanks below.

each additional copy (choose one) the time by seconds.

Explanation:

Step1: Find the difference between 2 and 1 copy

To see how much time increases per copy, subtract the time for 1 copy from 2 copies. So, \(17 - 10 = 7\) seconds.

Step2: Check with 3 and 2 copies

Subtract time for 2 copies from 3 copies: \(24 - 17 = 7\) seconds.

Step3: Check with 4 and 3 copies

Subtract time for 3 copies from 4 copies: \(31 - 24 = 7\) seconds.
Since each time the number of copies increases by 1, the time increases by 7 seconds. So the operation is "increases" and the number of seconds is 7.

Answer:

Each additional copy \(\boldsymbol{\text{increases}}\) the time by \(\boldsymbol{7}\) seconds.
