A management engineering team calculated 162 total monthly man-hours. If the workweek is 40 hours and 7.7 percent is applied, how many additional requirements does the shop receive?

To determine the additional requirements the shop receives, it’s important to first understand the total man-hours available and how the adjustment percentage impacts that figure.

The total monthly man-hours calculated is 162. In a standard workweek, which comprises 40 hours, we need to convert this into how many total workweeks are represented in those man-hours. Since there are about four weeks in a month, the total available man-hours for the month is calculated as:

40 hours/week * 4 weeks = 160 hours.

Now, applying the 7.7% increase to the available total hours is crucial to find out how many additional requirements are needed. The formula for determining the increase based on the percentage is:

Additional man-hours = Total man-hours * (Percentage / 100)

So, we have:

162 man-hours * (7.7 / 100) = 12.474 additional hours.

To convert this additional requirement into complete workweeks, we then divide the additional hours by the number of hours in a week:

12.474 additional hours / 40 hours/week = 0.31185.

Since you cannot have a fraction of an employee in this context, you would round this number to the nearest whole number. This results
