A student claims that the expression “9 times the sum of a number and 13” is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?

9*13+n 
I think that is correct, try and split up the question. 
9* 
A sum of a number AND 13
So that means that 9 is multiplying by the SUM (adding) of 13 and a number (n)

9*13+n 

9* 
A sum of a number and 13

so your answer is correct.
