If David's new job pays $2400 per month, then his yearly salary at his new job would be $2400 x 12 = $<<2400*12=28800>>28,800 a year.
Therefore, the correct answer is $28,800 a year.
To find David's yearly salary at his old job, we need to divide his new monthly salary ($2400) by 5.
2400 / 5 = $<<2400/5=480>>480
So David's yearly salary at his old job was $480.
