Question

Jonathan subtracted two numbers with a difference of 12.67 and added two numbers with a sum of 12.67. What is the result?

a) 25.34
b) 0
c) 12.67
d) 6.335

Answer 1

Combining Jonathan's subtraction result (12.67) with his addition result (12.67), we get a total of 25.34. Thus, the correct answer to the student's question is 25.34.

Step-by-step explanation:

When Jonathan subtracted two numbers, he got a difference of 12.67, and when he added two numbers, he got a sum of 12.67. To find the overall result of both the subtraction and the addition, we need to combine the two separate outcomes. Here's how it works:

• Subtraction: One unknown number minus another unknown number equals 12.67.
• Addition: One unknown number plus another unknown number equals 12.67.

When we add these two results together- the difference (12.67) and the sum (12.67)- we get:

12.67 + 12.67 = 25.34

Therefore, the final result Jonathan would get after performing both operations is 25.34.

So the correct answer is: a) 25.34
