Answer 3

Problem Analysis

We are given that the first machinist can print 72 sheets in 8 hours. We need to find out how many sheets the second machinist can print in the same amount of time, given that she prints 3 sheets less per hour than the first machinist.

Solution

To find out how many sheets the second machinist can print in 8 hours, we need to subtract 3 sheets from the first machinist's hourly rate and multiply it by 8.

Let's calculate it step by step:

1. Find the first machinist's hourly rate: - The first machinist can print 72 sheets in 8 hours. - Therefore, the first machinist's hourly rate is 72 sheets / 8 hours = 9 sheets per hour.

2. Find the second machinist's hourly rate: - The second machinist prints 3 sheets less per hour than the first machinist. - Therefore, the second machinist's hourly rate is 9 sheets per hour - 3 sheets per hour = 6 sheets per hour.

3. Calculate the total number of sheets the second machinist can print in 8 hours: - The second machinist's hourly rate is 6 sheets per hour. - Therefore, the second machinist can print 6 sheets per hour * 8 hours = 48 sheets in 8 hours.

Answer

The second machinist can print 48 sheets in 8 hours.

Verification

Let's verify the answer using the given information:

- The first machinist can print 72 sheets in 8 hours. - The second machinist prints 3 sheets less per hour than the first machinist. - Therefore, the second machinist's hourly rate is 9 sheets per hour - 3 sheets per hour = 6 sheets per hour. - The second machinist can print 6 sheets per hour * 8 hours = 48 sheets in 8 hours.

The answer is consistent with the given information, so it is correct.
