3. Volunteers work for your non-profit for 2 weeks at a stretch in the summer. The total time span is 6 weeks where you need volunteers. You need 10 in week 1, 7 in week 2, 8 in week 3, 12 in week 4, 7 in week 5 and 7 in week 6. Those who begin work in any of the first 5 weeks continue to work for 2 weeks from the time they begin. However, those you begin in week 6 only work for that week, and then your summer project is done. How would you minimize the number of volunteers needed to satisfy the requirements
