SAT Math... again

posted by .

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

  • SAT Math... again -

    If Nora is n years old NOW, then Kevin is NOW n-3

    so 4 years ago Kevin was (n-3) - 4
    = n - 7 , (E)
