Here's an example: I hope this helps you out
<span>3 feet make 1 yard.
40 feet make 13 and 1/3 yards
So that is 13 yards to nearest </span>
Enrique+levi=386
enrique=221
subsitute
221+levi=386
subtract 221 frm botoh sides
levi=386-221
levi=165
levi has 165 cards
I believe the answer is d, because i cant find a pattern where x and y are directly connected.
