Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! let x be the number of hours, then
250 +14x < 22x
subtract 14x from both sides of =
250 < 8x
31.25 < x
number of hours must be greater than 31.25 hours
as a check suppose the job takes 32 hours, then
250 + 14*32 < 22*32
698 < 704
the answer checks out
