Joseph completed the two-way table on the left about the social networking habits of his classmates as follows: step 1: 85 – 30 = 55 step 2: 80 – 55 = 25 step 3: 140 – 80 = 60 step 4: 60 – 30 = 30 step 5: 25 + 30 = 55 choose one option from below the student a) and error in step 1 b) and error in step 2 c) an error in step 3 d) an error in step 4 e) an error in step 5 f) no error

Joseph made no error.

The answer is F) no error

Option: F is the correct answer.

F) No error.

Step-by-step explanation:

We are given the steps that Joseph used while solving as:

Step 1: 85 – 30 = 55

Step 2: 80 – 55 = 25

Step 3: 140 – 80 = 60

Step 4: 60 – 30 = 30

Step 5: 25 + 30 = 55

Clearly the steps involves simple addition as well as subtraction of the mathematical numbers.

Hence all his steps are correct as he has not committed any wrong operation.He evaluated the expressions in the right manner.

          Hence, the answer is:

                    Option: F
