Question:
A restaurant is trying to make up its mind about whether it should clean or buy new napkins every day.
There is a trade-off in cost: $10 for a new napkin, $2 for 1 day cleaning, $1 for 2 day cleaning.
The need for napkins are 100 Monday to Friday and 125 on the weekend.
What is the optimal number of new, 1 day cleaned, and 2 day cleaned napkins to minimize the cost and meet demand?
On problem 2, treat the new napkins as disposables - you use them for a day and toss them. So they effectively have zero cleaning time.
If I use a new napkin, it's used on Monday and that's the end of it.
If I use a 1 day napkin on Monday, I have to wait until Wed to reuse it.
If I used a 2 day napkin on Monday, I have to wait until Thursday to reuse it.
