Exercise 21

Use ratio and proportion to solve the following business situations.
You have just been hired as advertising manager of The Daily Chronicle , a not-very-successful newspaper. In the past, The Chronicle contained one-half advertising and one-half news stories. Current industry research indicates a newspaper must have three times as much advertising as news stories to make money. In addition, the advertising must be divided in the following ratio: 5 to 3 to 1, retail advertising to national advertising to classified advertising. The Chronicle is typically 48 pages in length.
a. How many pages should be advertising, and how many should be news stories
b. Based on the industry ratios, how should the pages be divided among the three types of advertising
c. After you made the changes in the advertising distributions ratios, your newspaper began making a profit-for the first time in years. If last year's total advertising revenue was $810,000, how much was earned by each type of advertising
d. When you accepted the job of advertising manager, in addition to your salary, you were promised a
share of each year's revenue from retail and classified advertising and a
share for national. What bonus will you receive for last year's sales
