Chapter 1.4, Problem 10E
Reminder: Round all answer to two decimal places unless otherwise indicated.
a. How much does it cost to prepare and mail a 3-page letter if your secretary spends 2 hours on typing and corrections?
b. Use a formula to express the cost of preparing and mailing a letter as a function of the number of pages in the letter and the time it takes your secretary to type it. Identify the function and each of the variables you use, and state the units.
c. Use the function you made in part b to find the cost of preparing and mailing a 2-page letter that it takes your secretary 25 minutes to type. (Note: 25 minutes is 25/60 hour.)
