Final answer:
There will be a total of 147 packages that will roll to the next cycle due to not having enough Flex Drivers, after accounting for the remaining 80 routes available and the Average SPR of 40 packages per route.
Step-by-step explanation:
The student is asking to calculate the volume of packages that will not be delivered (rolled to the next cycle) due to a shortage of Flex Drivers. Since the Average SPR (average number of packages per route) for Flex routes is 40 and the total Flex pool for any given day is 120 routes, we need to find out how many routes will be left after 40 routes have already been used earlier in the day. Thus, 120 - 40 gives us 80 routes available for the ADHOC sort.
To find out how many packages can be accommodated by the 80 routes, we multiply the number of routes by the Average SPR, which is 80 routes * 40 packages per route equals 3200 packages that can be delivered.
Since there are 3347 packages in total, we subtract the number of packages that can be delivered (3200) from the total number of packages (3347) to get the volume that will roll to the next cycle, 3347 - 3200 equals 147 packages.
