At a certain department store present-wrapping counter, each clerk will wrap no fewer than 20 and no more than 30 presents per hour. If seventy people are waiting in line, will all their presents be wrapped after one hour?
1) Each person in line has at least one present to be wrapped by one of the six clerks at the counter.
2) If each person in line had one more present to be wrapped, nine clerks would be required to guarantee that every gift would be wrapped in one hour.
pl explain you approach. thanks.
