In this exercise, we will tackle a classic problem that tests your ability to follow through multiple steps to reach the correct solution. Here is the problem statement:

Problem Statement

• $5 per page for the first time a page is typed.
• $3 per page each time a page is revised.

• The manuscript has 100 pages in total.
• 40 pages were revised only once.
• 10 pages were revised twice.
• The rest of the pages had no revisions.

Task

Calculate the total cost of having the manuscript typed.

Clue

Do not be misled by solving only the initial part of the problem correctly. There are multiple steps involved, and the trick lies in considering all aspects of the problem.

Breakdown of the Problem

1. Initial Typing Cost: Calculate the cost for typing all 100 pages for the first time.
2. First Revision Cost: Calculate the cost for revising the 40 pages that were revised once.
3. Second Revision Cost: Calculate the cost for revising the 10 pages that were revised twice.
4. Total Cost: Sum up all the costs from the above steps to get the total cost.
