An online job seeking service allows job seekers to post their resumes for free. The service charges employers looking for applicants a fee to look through the resumes. The fee is based on how long the employer wants access to the resumes, and how many miles from the workplace address the employer wants to consider. The fees are $585 for a 100-mile radius for 3 weeks and $675 for a 150-mile radius for 3 weeks.
a. If there are 98 resumes within a 100-mile radius, what is the average cost to the nearest cent to the employer for looking at each resume?
b. If there are 208 resumes within a 150-mile radius, what is the average cost to the employer for looking at each resume?
c. Under the 150-mile radius option, an employer would see the same 98 resumes from part a that he would have seen under the 100-mile radius option. What is the average cost to the employer for looking at the extra resumes he would see if he opted for the more expensive plan? Explain.
d. Give an advantage and a disadvantage of opting for the more expensive plan.
