Bella is planning to write in a journal. Some pages will have one journal entry on them, and other pages will have two journal e
ntries on them. If Bella wants to make 10 entries, how many different ways can she write them in her journal?
I've already seen an answer someone did by diagramming each of the actual coins, but is there an equation I can use, not just for this problem, but also other problems of this type? Thanks!
<span>1 page with 10. 2 pages with five entries each. 5 pages with
2 each. There are many more way such as
3 pages 2 with three entries and one with 1 entry. 4 pages with 2 entries and 1 with 4 </span>
To find out how many games Chris sold, we have to take the average and subtract 17.
Since there are no more values we can use, this is as simple as we can get it. If we knew how many games they sold last month, we could get an exact answer for Chris using this expression.
