If it is assumed that 60 percent of those who receive a questionnaire…

Solution:

We are given that 60% of those who receive a questionnaire will respond. We must determine how many questionnaires need to be mailed to receive 300 responses. If we let n = the number of questionnaires sent, we can create the following equation:

0.6n = 300

6n = 3,000

n = 500

Answer: D
