  A computer manufacturer assembled 21,000 computers in October. For the month of November, they expect to double production. If a worker can assemble one computer per day, how many workers will be needed to complete the job in 28 days?
  
  a. 1,500 workers
  b. 750 workers
  c. 1,429 workers
  d. 4,500 workers
  
  21,000 / 28 = ?
  
  I think you would then multiply that by 2, since it says to expect double production..?
  
  Oops! You're right, Jen. :-)
  
  42,000 / 28 = ?
