SAT Math... again

I asked two questions yesterday, and thankfully, bobpursley answered the latter. I accidentally typed in the first question wrong, so I'd really appreciate it if someone helps me out.
Thank you, and have a good day :)
1. Kevin is 3 years younger than Nora. If n represents Nora's age now, what was Kevin's age 4 years ago, in terms of n?
A. N + 7
B. N + 1
C. N  1
D. N  4
E. N  7

If Nora is n years old NOW, then Kevin is NOW n3
so 4 years ago Kevin was (n3)  4
= n  7 , (E)
