Jillian was asked to translate the expression 9 + n into words. She wrote "a number increased by nine." Which best describes the accuracy of Jillian's answer?

A. It is incorrect. The variable would come first in the expression "a number" (n) "increased by" (+) "nine" (9).

B. It is incorrect. The phrase "increased by" refers to the inequality symbol "greater than" (>), not addition.

C. It is correct. A number increased by nine (n + 9) is the same as nine increased by a number (9 + n).

D. It is incorrect. A number increased by nine refers to a multiplication expression (n x 9).

I think it's C but just to check I'll post it here.
