WILL GIVE MEDALS A box company completed a study to determine the number of boxes an old machine would produce in an hour. They determined that the old machine produced 280 boxes in 4 hours.

Which of the following is true about the new machine?

OpenStudy (anonymous):

The new machine can produce 14 boxes an hour. The equation y = 84x represents the production rate of the new machine. The new machine can produce 7 more boxes an hour than the old machine. The equation y = 77x represents the production rate of the new machine.
