Suppose that 6 people can stuff flyers into 500 envelopes in 5 minutes. Assume all people work at the same steady rate.
a. The relationship between the number of people stuffing envelopes and the number of minutes it takes to stuff flyers into 500 envelopes is what type of relationship? How can you tell? Make a table and a graph to show the relationship and explain how to find several of the entries. Include an entry for 5 people.
