Correct answers:
- The equation y = 77x represents the production rate of the new machine.
- The new machine can produce 7 more boxes an hour than the old machine.

Work: old machine = 280/4 = 70 boxes/hour. In 8 hours old machine would make 70·8 = 560; new made 560 + 56 = 616 in 8 hours, so new rate = 616/8 = 77 boxes/hour (which is 7 more than 70).
