Kelley writes the expression n+2 to model the phrase "Xander studied two more hours than Nandini." Which best explains the accuracy of Kelley's expression?

A.) It is accurate. In the phrase "two more hours than Nandini," "two" is "2," "more" is "+," and Nandini's study time is unknown or "n," so 2+n or n+2 are correct translations.

B.) It is inaccurate. In the phrase "two more hours than Nandini," "two" is "2," "more" is "+," and Nandini's study time is unknown or "n," so 2+n is the correct translation.

C.) It is inaccurate. In the phrase "two more hours than Nandini," "two" is "2," "more than" is ">," and Nandini's study time is unknown or "n," so 2>n is the correct translation.

D.) It is inaccurate. In the phrase "two more hours than Nandini," "two" is "2," "more than" is "<," and Nandini's study time is unknown or "n," so 2

Answer: A.) It is accurate. In the phrase "two more hours than Nandini," "two" is "2," "more" is "+," and Nandini's study time is unknown or "n," so 2+n or n+2 are correct translations.

Step-by-step explanation:

Here, n is unknown variable, thus it must represent the number of hours Nandini studied.

If Xander studied two more hours than Nandini.

Then, the number of hours Xander studied = n + 2 or 2 + n

Hence, kalley wrote a right expression.

⇒ Option A is correct.
