The first candidate’s training will cost 1200 * 3 = $<<1200*3=3600>>3600.
That candidate will make the company 93000 - 42000 - 3600 = $<<93000-42000-3600=47400>>47400 in the first year.
The second candidate’s bonus will cost 45000 * 1 / 100 = $<<45000*1/100=450>>450.
That candidate will make the company 92000 - 45000 - 450 = $<<92000-45000-450=46550>>46550 in the first year.
Thus, the first candidate will make the company 47400 - 46550 = $<<47400-46550=850>>850 more in the first year.
