I have a homework problem that asks me to do the following:

Question

1. Prepare a schedule of total cash collections for October through December.
2. Prepare a schedule of total cash disbursements for October through December.
3. Prepare a cash budget for October through December.
I know basically how to do that, but the teacher added the following bit that I am not sure what to do with: *Uncollectibles amounting to 5% of sales are anticipated, and management believes that only 15% of the accounts outstanding on September 30, 2014, will be recovered and that the recovery will be in October 2014.* Where (one or all of #1, #2, #3) and how to I account for this? All the other problems we have done told us to ignore uncollectables but this seems to imply something else. And there are no examples in our book like this one. Help! Thank you :)
