Answer 2

Calculation Method 1: Using Total Hours

To calculate the total number of pages the typist printed, we can add up the number of hours she worked each day and multiply it by her page-per-hour rate.

The number of hours the typist worked each day: - Monday: 4 hours - Tuesday: 2 hours - Wednesday: 3 hours

To find the total number of pages, we need to calculate the total number of hours worked and multiply it by the page-per-hour rate.

Total hours worked = 4 hours + 2 hours + 3 hours = 9 hours

Page-per-hour rate = 5 pages per hour

Total number of pages printed = Total hours worked * Page-per-hour rate = 9 hours * 5 pages per hour = 45 pages.

Calculation Method 2: Using Daily Totals

Alternatively, we can calculate the total number of pages printed by summing up the pages printed each day.

Pages printed on each day: - Monday: 4 hours * 5 pages per hour = 20 pages - Tuesday: 2 hours * 5 pages per hour = 10 pages - Wednesday: 3 hours * 5 pages per hour = 15 pages

Total number of pages printed = Pages printed on Monday + Pages printed on Tuesday + Pages printed on Wednesday = 20 pages + 10 pages + 15 pages = 45 pages.

Therefore, using both calculation methods, we find that the typist printed a total of 45 pages.
