For 1 copy it takes 5 seconds, for 2 copy it takes 7 seconds, and for 3 copy it takes 9 seconds.
For each copy, it takes 2 seconds more.
Step-by-step explanation:
A teacher is making multiple copies of a 1-page homework assignment. The time it takes her in seconds is 2 times the number of copies she makes plus 3. What is the total number of seconds it takes for the teacher to make 1 copy? 2 copies? 3 copies? By how many seconds does the total time increase for each copy?
Let the number of copies represented by x and y is the time taken.
The time It takes her in seconds is 2 times the number of copies she makes plus 3.
So the required equation is
.
To calculate the time taken for the first copy put x=1 in the above equation.
To calculate the time taken for the first copy put x=2 in the above equation.
To calculate the time taken for the first copy put x=3 in the above equation.
Hence, For each copy, it takes 2 seconds more.
