an office where 8 secretaries work 8 hours a day 5 days a week decided it needs 336 hours a week of secretarial work. How much more or less will each secretary have to work each week to equally share the 336 hours.
8 * 8 * 5 = 320 current hours
(336 - 320)/8 = ______ more hours for each person per week
8 * 8 * 5 = 320
336 - 320 = ?
Divide that among 8 secretaries.
To find out how much more or less each secretary will have to work each week to equally share the 336 hours, let's break down the problem step by step:
1. Calculate the total number of work hours required per week: Multiply the number of secretaries (8) by the number of hours each secretary works per day (8) and the number of days they work per week (5).
Total work hours per week = 8 secretaries × 8 hours/secretary × 5 days/week
Total work hours per week = 320 hours
2. Find the difference between the required hours (336 hours) and the total work hours per week (320 hours).
Difference = Required hours - Total work hours per week
Difference = 336 hours - 320 hours
Difference = 16 hours
3. Divide the difference by the number of secretaries to determine how much more or less each secretary has to work.
Change in work hour per secretary = Difference / Number of secretaries
Change in work hour per secretary = 16 hours / 8 secretaries
Change in work hour per secretary = 2 hours
Therefore, each secretary will have to work 2 hours more per week to equally share the workload of 336 hours.
