Balancing Equations - can someone please check this

I think I understand balancing equations, but one answer in my crappy OCR text book has me doubting myself.

Unbalanced


Fe2O3+CFe_{2}O_{3}+C ---> CO+FeCO+Fe

I get:

Fe2O3+3CFe_{2}O_{3}+3C ---> 3CO+2Fe3CO+2Fe

OCR says it is:

2Fe2O3+3C2Fe_{2}O_{3}+3C ---> 3CO+4Fe3CO+4Fe
