Problem: There are $5$ items and cost of these items in dollars are $3$, $3.2$, $4.5$, $2.5$, $1.7$ respectively. How can we allocate $100$ dollars to buy the above items in a such way in order to get **maximum number of items** in our hand.

1. All types of items should be covered
2. Repetition of items may be allowed
3. Maximum number of items should be purchased
4. Not necessary to spend entire $100$. but, maximum amount should spend near to $100$ or with entire $100$
5. We need to buy each kind of item as much as possible

How to solve this type of problem?
Kindly answer
Thanks again
