Question 250149: A building contractor agrees to pay a fine for all the days he is late completing a job. The penalty for being one day late is set at $45. Each day after that, the penalty is increased by $10, and it is cumulative! If the contractor's penalty turns out to be $1725, how many days late is he in completing the job?
Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
if it costs $45the first day and each subsequent day costs $10
dayone =45
others=10d
dayone + others=1725
we have 45+10d=1725
solve for d and add one for the first day
The contractor was very late.
Don't use that contractor and/or charge a lot more per day
