Question: Rachel is stuffing envelopes. She has eight hours to complete the task, and there are 1,500 envelopes. In the first hour, Rachel stuffs 135 envelopes. The second hour she stuffs 141 envelopes. How many envelopes will Rachel need to stuff per hour to finish the job? Is final answer 204?
Answer: Rachel has 1500 - 135 - 141 envelopes = <<1500-135-141=1224>>1224 envelopes remaining to stuff.
Rachel has 8 hours - 2 hours = <<8-2=6>>6 hours left to finish the task.
Rachel needs to stuff 1224 envelopes / 6 hours = <<1224/6=204>>204 envelopes per hour.
